Chapter 7 Max. Guarantee Time for Data Communication
Chapter 7 Max. Guarantee Time for Data Communication
7.1 Maximum guarantee time for communication between stations
The maximum guarantee time for data communication between stations is the maximum time which may be required for a sender station to transmit data to a receiver station. Therefore, the data which change by shorter cycle than this time cannot be guaranteed for reliability. The maximum guarantee time for data communication between stations depends upon the No. of stations in the communication network, No. of transmission parameters of the stations, and the program scan time of the communication PLC.

1. Transmission PLC Delay Time (sender station) (2 times the max. scan time) + 20msec (time for data move from CPU to FNET module)
2. Reception PLC Delay Time (receiver station) (2 times the max. scan time) + 20msec (time for data move from CPU to FNET module)
3. Transmission time (max. token guarantee time No. of tokens required for the sender) The max. token guarantee time is the total time of the token holding time of the station, calculated by 1.6 + 1.5 Nm(note1) per station. The No. of the tokens required for transmission is calculated by dividing the No. (N) of transmission blocks of the sender station with No. of the process blocks(note2) per token plus one if there is remainder (add 2 instead of 1 as safety factor). E.g.) In an XGT series with 20 transmission blocks, the 3 tokens are required for data transmission.
4. Max. Guarantee Time for Inter-Station Data Communication Transmission PLC delay time + reception PLC delay time + transmission time
   If the No. of transmission blocks of the stations is not available, assume the token holding time of the station to be the maximum value, which is 1.6 + 1.57 = 12.1(msec) for XGT and 1.6 + 1.510 = 16.6 (msec)(note3) for GM/MK. However, of all the stations, the No. of the transmission blocks of the sender station must be known.
   Notes [1] Nm is the No. of the transmission blocks set up for each station. The maximum of XGT and GM/MK shall be 7 and
   10, respectively. [2] No. of processed blocks per token
   -XGT: 7 -GM/MK: 10 [3] Constant for calculating token holding time – 1.6 msec: time required for processing token – 1.5 msec: time required for sending a 60 word frame
   7-1

Chapter 7 Max. Guarantee Time for Data Communication

7.2 Calculation of the Max. Guarantee Time for Data Communication between
Stations
The case below is based on; an XGT series having the station numbers and transmission blocks as presented below; program scan of each station is 10msec, and; the time required for the station 4 transmitting data to the station 1.

Station No. 1 2 3 4 5

No. of Blocks 3 5 10 20 32

1. For max. token guarantee time, calculate the token holding time of the stations as shown below, and add up.

Station No. 1 2 3 4 5

No. of Blocks 3 5 10 20 32

Token holding time (sec) 1.6 + 1.53 = 6.1 1.6 + 1.55 = 9.1 1.6 + 1.57 = 12.1 1.6 + 1.57 = 12.1 1.6 + 1.5*7 = 12.1

2. Since the max. token guarantee time is the sum of the token holding time of the stations;

6.1 + 9.1 + 12.1 + 12.1 + 12.1 = 51.4 (msec)

3. The time required for the station 4 to send data to the station 1

Station No.

No. of Blocks

No. of tokens required for station 4

Transmission Time (msec)

3*51.4=154.2

4

20

20/7=28.5=3

When add 1 to the No. of tokens for safety, the result is

205.6

4. Delay time of the sender (station 4): 2 10msec + 20 msec = 40 msec 5) Delay time of the receiver (station 1): 2 10msec + 20 msec = 40 msec 6) Max. guaranteed data communication time between stations = (Sender PLC delay time)

• (receiver PLC delay time) +
  (transmission time), therefore, 40 + 40 + 154.2(205.6) = 234.2 or 285.6 (msec)

Therefore, the signals changing at the cycle longer than 234.2 or 285.6 msec can guarantee reliable communication. In particular, correct data communication can be guaranteed when the communication cycle is set to be longer than the maximum guarantee time for inter-station data communication.

7-2

Chapter 7 Max. Guarantee Time for Data Communication

7.3 Master Switching Time
Any station in the FNET can be a master station through competition for master. The station then acts as the LAS station and other stations act as slave stations. If the master is disabled for any reason, other stations compete for the mastership. This takes a little time which can be calculated as follows.
(Station No. + 0x10) 2 128 (usec) (Station No. + 0x10) 128 (usec) (0 ~ 63) 128 (usec) 1msec (RT frame transmission time)

The master switching time is determined by the sum of the above four factors. Due to the factor , the switching time becomes

uncertain. The max./min. switching time for the stations are as follows.

.1 Terms and Definitions

1. Self station
   The Fnet I/F modules currently connected with XG5000. Usually, of the Fnet I/F modules installed in the current PLC, those which are connected to XG5000 and monitored and diagnosed.
2. Destination station
   Other F-net I/F modules connected with the self station via Fnet. Usually refers to the Fnet I/F modules installed in other PLCs, the Fnet I/F modules installed in other slots of the current PLC may in this category.
3. Local Station
   The module type which can act as a master (LAS) in the Fnet. The XGL-FMEA I/F module acts as a master only. – GM/MK series has remote stations in addition.
4. Remote Station
   The opposite concept of the local station. As a partner station for communication with local station, a remote stations cannot conduct the role of LAS which controls token.
5. Fnet
   Fieldbus is a middle/lower tier network which connects controllers and measuring instruments, or between controller. The specification adopts 3 tiers of the tiers of OSI. The 3 tiers are; the physical layer including H2 (1Mbps Electric), H1 (31.23Kbbs Electric), optic, wireless, etc.; data link layer adopting Scheduled and Circulated Token bus, and; the application layer which processes applications, and further, added with a user layer. Difference from R-net, Peer to Peer communication is supported.
6. Token
   The authority of transmitting data by controlling the access to physical medium.
7. Repeater
   Used to extend cables in communication networks by regeneration and amplification of electric signals.
8. Manchester Biphase-L
   A data modulation method used in Rnet. Data are encoded using Manchester-I Code and transmitted. The data received by encoded with Manchester is decoded.
9. Individual Module Reset
   A function used for system initialization in the event of an error in communication module. In the XG5000, select [Online] [Reset/Clear] [Reset individual Module] to conduct reset. When this function is executed, the communication module restarts.
10. Active Coupler
    A module connecting the optic modules in a network. An optic splitter which can regenerate and amplify optic signals.
    A-1

APPENDIX
11) E.O.C (Electric/Optic Converter)
A module converting optic signals into electric signals and vice versa, in addition to signal regeneration and amplification
12) CRC (Cyclic Redundancy Check)
A method of error detection widely used in synchronous communication.
13) Terminating Resistor
The resistor used for impedance matching between the transmitter and receiver on a physical layer. The terminating resistor of Fnet is 110,1/2 W
14) HS (High Speed) Link
A communication method applicable for Fnet communication modules only. Used for high speed data communication by HIGH SPEED LINK ling parameter setting of XG5000 and GMWIN/KGL-WIN.
15) Segment
A local network where all the stations are connected using the same token, not using any connection device such as gateway, EOC or repeater.
16) Network
A communication system comprising one or more segments and using the same token.
17) LAS Creation and Transfer Method
LAS is created in FMM communication modules in following cases. (1) Of all the stations connected to the network, the FMM communication module whose power is turned on earlier than
all others acquires the LAS (2) If two or more stations are powered on at the same time, the station of the lower station number gets the LAS. (3) If the LAS station fails during normal communication, the LAS is transferred to the FMM station having the lowest
station number. (4) Only one LAS exists in a network

Description

Detail Explanation

All the stations are working normally according to the parameters set up in

the HSL. This flag is ON under following conditions.

All the stations of HSL – all the stations set up in the parameter are in RUN mode without error,

Bit

parameter #1 are operating – all the data blocks conduct normal communication, and

normally

– when the parameters set up in the stations themselves are normally

communicated, the RUN_link, if once turned on, keeps on unless

interrupted by link disable.

This flag is on when the _HSm_RLINK flag is on and the communication

between the stations set up in the parameters and data block are as

follows;

Bit

After _HS1_RLINK ON, – the station set up in the parameter is not in RUN mode, abnormal state is indicated – the station has an error, or

-if the data block’s communication is not smooth, the link trouble will turn on if the above conditions 1, 2, or 3 occurs, and turns off when the above

conditions are corrected.

Remark Comparing to the HSL #1 of the [Table 1], the flag address No. of other HSL station No. can be calculated with the formula below.
L Area Address No. = L000000 + 500 x (HSL No. ­ 1)
To use HSL flag for programming and monitoring, it is convenient to use the flag map registered in the XG5000.

Ex) k is the block number, which shows the information of the 128 (1~127) blocks with 8 words (16 blocks per word). For example, the mode information (_HS1_MOD) shows from block 0 to block 15, blocks 16~31, 32~47, 48~63, 64~79, 80~95, 96~111, and 112~127 in the L00010, L00011, L00012, L00013, L00014, L00015, L00016, and L00017, respectively.
