invt IVC1L-5AM Analog I-O Module

Thank you for using INVT programmable logic controller (PLC). Before using the IVC1 L series PLC product, please carefully read this booklet so as to better understand it, fully use it, and ensure safety.

Port Description

Port

The extension port and user port of IVC1 L-5AM are both protected by a cover, as shown in Figure 1-1. Removing the covers reveals the extension port and user port, as shown in Figure 1-2.

The extension cable connects IVC1L-5AM to the system, while the extension port connects IVC1 L-5AM to another extension module of the system. For details on connection, see 1.2 Connecting Into System. The user port of IVC1 L-5AM is described in Table 1-1.

Note: an input channel cannot receive both voltage signals and current signals at the same lime. If you intend to use a channel for current signal measurement, short its voltage input terminal and current input terminal.

Connecting Into System

Through the extension cable, you can connect IVC1 L-5AM to IVC1 L series basic module or other extension modules. While through the extension port, you can connect other IVC1 L series extension modules to IVC1 L-5AM. See Figure 1-3 .

Wiring

The wiring of user port is shown in Figure 1-4.

The circled 1-9 stands for the six points to be observed during wiring:

1. It is recommended to use shielded twisted pair for the analog input and output. Route them separate from power cables or any cables that may generate EMI.
   If the 1/0 signal has electric noise or voltage fluctuation, it is advisable to connect a smoothing capacitor (0.1 μF-0.47μF/25V).

2. If strong EMI exists, connect the FG and PG terminals together.

3. Each load of the PLC should be grounded separately.

4. If a channel is used for current input, short its voltage input terminal and current input terminal.

5. Shorting the voltage output terminals or connecting current load to the voltage output terminals may damage IVC1 L-5AM.

6. Properly ground the module’s PG terminal.

7. The basic module’s 24Vdc output power or any qualified external power supply can be used as the power source of the module’s analog circuit.

8. Do not use the NC terminal of the user port.

Buffer Memory

IVC1 L-5AM exchanges data with the basic module through Buffer Memory (BFM). After IVC1L-5AM is set through the host software, the basic module will write data into IVC1 L-5AM BFM to set the state of IVC1 L-5AM and display the data from IVC1 L-5AM on the host software interface. See Figure 4-1 and
Figure 4-1.
Table 2-3 describes the contents of IVC1L-5AM BFM.

Explanation:

1. CH 1 stands for channel 1; CH2, channel 2; CH3, channel 3, and so on.

2. Property explanation: R means read only. An R element cannot be written. RW means read and write. Reading from a non-existent element will get 0.

3. Status information of BFM#300 is shown in Table 2-4.

4. BFM#600: input mode selection, used to set the input modes of CH1-CH4. See Figure 2-1 for their correspondence The exact meaning of the X in the channel mode is shown in Table 2-5.
   Table 2-5 Meaning of X in input mode
   For example, if #600 is written as ‘0x0103’, the setting will be like this:

5. Input channel 1 closed;

6. Input channel 3 mode: -5V-+5V or -20mA-20mA (note the wiring difference in voltage and current, see 1.3 wiring);

7. Input CH2, and CH4 mode: -10V-+10V.

8. BFM#650: output mode selection, controlled by the X1 in the 4-bit hexadecimal number 0xX4X3X2X 1- The meaning of X is as follows:
   Table 2-6 Meaning of X in output mode

9. BFM#700-BFM#703: average sampling times setting; setting range: 1-4096. Default: 8 (normal speed); choose 1 if high speed is needed.

10. BFM#900-919: channel gain and deviation settings, which are set using two-point method. DO and D1 represent channel digital output, AO and A1 represent actual channel input. AO and A1 are in mV or μA, and each channel occupies 4 words. To simplify the setting operation without affecting functions, AO and A 1 are respectively fixed to 0 and the max value. Users cannot change them.
    Note: If the channel input is current signal (-20mA-20mA), the present channel mode should be set to 1. Because the channel’s internal measurement is based on voltage signal, current signals should be converted into voltage signals (-5V-5V) by the 2500 resistor at the current input terminal of the channel. The A 1 in the channel’s characteristics setting is still in mV unit, i.e., 5000mV (20mA x 2500 = 5000mV).

11. BFM#2000: AD conversion speed setting. 0: 15ms/channel (normal speed); 1: 8ms/channel (high speed). Setting BFM#2000 will restore BFM#1–#2 to the default, which should be noted in programming. If necessary, you can reset BFM#700-#703 after changing the conversion speed.

12. BFM#4094: module software version, displayed automatically as Module Version in IVC1 L-5AM Configuration dialogue box of the host software, as shown in Figure 4-2.

13. BFM#4095: module ID. ID of IVC1 L-5AM is 0x3141. The user program in PLC can use this ID to identify the module before transceiving data.

Characteristic Setting

Setting Analog Input Channel Characteristics

The input channel characteristic of IVC1 L-5AM is the linear relationship between the channel’s analog input A and digital output D. It can be set by the user. Each channel can be considered as the model shown in Figure 3-1. As it is of linear characteristic, the channel characteristic can be defined by just two points: PO (AO, DO) and P1 (A1, D1), where DO is the channel’s digital output corresponding to analog input AO, and D1 is the channel’s digital output corresponding to analog input A 1.

To simplify the operation process without affecting functions, AO and A1 are respectively fixed to 0 and the maximum value in the present mode. That is to say, in Figure 3-1, AO is 0 and A1 is the maximum analog input in the present mode. AO and A1 will change according to the mode when BFM#601 is changed. Users cannot change their values.
If you just set the channel mode (BFM#601) without changing the DO and D1 of the corresponding channel, the channel characteristic vs. mode should be as shown in Figure 3-2. The A in Figure 3-2 is default.

You can change the channel characteristic by changing DO and D1. The setting range of DO and D1 is -10,000-10,000. If the setting is outside this range, IVC1 L-5AM will not accept it, but maintain the original valid setting. Figure 3-3 provides for your reference an example of changing channel characteristics .

• Mode 0, DO= 0, D1 = 10,000 Mode 1, DO = -500, D1 = 2000
• Analog input 10V outputs 10,000 input 5V (or 20mA) outputs
• Analog input 0V outputs 0
• Analog input -1 0V outputs -10,000
• Analog input 1V (or 4mA) outputs 0
• Analog input -5V (or -20mA) outputs -3000

Setting Analog Output Channel Characteristics

The analog output channel characteristic of IVC1 L-5AM is the linear relationship between the channel’s analog output A and digital input D. It can be set by the user. Each channel can be considered as the model shown in Figure 3-4. Because ii is of linear characteristic, the channel characteristic can be defined by just two points: PO (AO, DO) and P1 (A1, D1), where DO is the channel’s digital input corresponding to analog output AO, and D1 is the channel’s digital input corresponding to analog output A1

To simplify the operation process without affecting functions, AO and A1 are respectively fixed to 0 and the maximum value in the present mode. That is to say, in Figure 3-4, AO is 0 and A 1 is the maximum analog output in the present mode. AO and A 1 will change according to the mode when BFM#600 is changed. Users cannot change their values.
If you set the channel mode (BFM#600) without changing DO and D1 of the corresponding channel, the channel characteristic vs. mode should be as shown in Figure 3-5. The A in Figure 3-5 is default

You can change the channel characteristic by changing DO and D1. The setting range of DO and D1 is -10,000-10,000. If the setting is outside this range, IVC1 L-5AM will not accept it, but maintain the original valid setting. Figure 3-6 provides for your reference an example of changing channel characteristics

• Mode 0, DO= 0, D1 = 10,000 Mode 0, DO = -500, D1 = 2000
• Digital input 10,000 outputs 10V Digital input 2000 outputs 5V (or 20mA)
• Digital input 0 outputs 0V Digital input 0 outputs 1 V
• Digital input -10,000 outputs -10V Digital input -10,000 outputs -5V

Application Example

Basic Application

IVC1-5AM is selected for both IVC1 L-5AM and IVC1-5AM in the system block.
Example : The IVC1L-5AM module address is 1 (for the addressing of extension modules, see IVG Series PLC User Manual). Use its channels 1, 2, 3 and 4 for voltage signal input (-1 0V-1 0V), set the average sampling times to 8, and use data registers D1, D2, D3 and D4 to receive the average value; set output channel to mode O to output 10V voltage signal, and use D5 element. Set extension module type as shown in Figure 4-1, and set actual parameters of extension module. Figure 4-2 shows the setting of input channel 1 and output channel 1. Set the other three input channels respectively in the same way .

To validate the parameter setting, you still need to compile and download the parameters. You can set and query D elements through the interface or by using the MOV instruction in user program.
MOV D5 2000 is a user program that makes the output channel output 10V.
For further details, see IVG Series PLC Programming Manual.
