Connections
The SlimLine Cortex M7 (LogicLab) CPU module is provided of extractable TB to connect Power, I/Os and Field bus, IDC connector to connect the extension modules, RJ45 connectors for RS232 COM ports and the Ethernet port, and one microUSB-AB connector
Power supply (Fig. 3)
The module can be powered with a DC source within the range 10-30Vdc. The
power connection must be done according to the Fig. 2.
The power is signalized by the green LED “PWR”.
WARNING! Values greater than the maximum allowed may damage the device seriously.
Ground connection (Fig. 2)
The device must be connected directly to Ground using the terminal block on
the power supply connector (Fig. 2).
The connection must be performed through a wire with section at least of
2.5mm2 , to a copper equipotential bar of adequate section.
To guarantee a good noise rejection, keep this connection as short as possible
and take care to place it far away to the other cables.
Digital and Analog Inputs (Fig. 3)
The module is provided of 2 digital input and 2 analog input (If any) The
digital inputs are galvanically insulated from the system and may be used as
PNP or NPN as for your convenience. The digital Input DI00 may be used as a
counter input with Fmax=10KHz.
Analog inputs (where provided) aren’t insulated from the system and accept
voltage from 0 to +10Vdc.
The module accepts two common mode analog input or, alternatively, one in
differential mode.
WARNING! To connect analog inputs use EXCLUSIVELY screened cables and be careful to place them away from noise sources.
Digital Outputs (Fig. 3)
The module is provided of 2 Optomosfet static digital outputs, galvanically insulated from the system. The outputs may be used either as PNP or NPN as for your convenience.
WARNING! Shorts on the outputs may damage permanently the device. It’s suitable to place an extra rapid fuse 250mAFF in series of the output common (i.e. Ferraz G084002P).
Extension bus and 1-wire bus (Fig. 9)
The communication bus with the extension modules uses the Fast I 2C™ interface
and it’s available on the IDC10 connector (P7).
The extension modules must be cascade connected through the special cables
CBL045*00/CBL074000.
The Fig. 10 is an example of extension modules connection. Up to 16
extension modules may be connected to the CPU. (after checking the maximum
current needed)
WARNING! Before to connect the extension modules to the system, be sure that it’s powered off. Missing this rule may produce failures in the modules.
The device may be equipped with a 1-WireTM bus (P11), through it you can acquire i-Button™ devices, such as TAG for personal identification, temperature sensors and other devices.
RS232 Serial ports (Fig. 8)
The device is provided of two serial ports DTE (Data Terminal Equipment). The
connection between DTEs, such as Personal Computers, Operator Terminals etc.,
must be done through a Nullmodem cable of maximum cable length of 15 mt,
according to EIA specifications.
These ports aren’t galvanically insulated from the system, it is recommended
to verify, before to connect together different devices, the difference of
potential on the ground.
WARNING! An excess of difference of potential on ground loop may cause damages to the devices.
Field bus (Fig. 8)
The module may be provided of a RS485 or CAN field bus (see product
identification Fig. 7 ), in both cases the bus is galvanically insulated
from the system. To connect the field bus please see Figure on side.
Through the LK4 jumper may be connected or not the 120 Ohm termination
resistor.
Ethernet port (Fig. 1)
The module is provided of an Ethernet 10/100-Base T(x) available on the RJ45
connector P6; the connection, shown in Fig. 1, is compatible with the
standard Ethernet IEEE 802.3 100-Base T.
To connect the device in an Ethernet network can be used UTP Cat. 5 cable
RJ45, connected to a switch, while to made a point to point connection it’s
enough to use an RJ45 patch cable alone. The device is Auto-MDIX, so no cross
cable is needed to connect it to a PC directly.
On P6 are available two LED for Ethernet status signaling: The green LED
signals, when on, that the network is running at 100Mb/s speed. The yellow LED
signals the Ethernet link activity. The module is supplied with DHCP enabled
and, in case of lack of a DHCP server, the IP address can be assigned with the
Toolly utility.
WARNING! The module is supplied with Admin user credentials: User “Admin” e password “Admin”. It is strongly recommended to change them before installation.
USB Host/Device port (Fig. 2)
The module may be equipped of a microUSB-AB port able to be used as host or device mode.
Slot SD Card (Fig. 6)
The module is provided of a slot mini-SD Card. The card may be used for archive functions or for data history functions during normal running. The card must be ordered separately.
Status signaling (Fig. 6)
The device is provided of some LEDs to signal its status:
-
PWR (Green LED)
Indicates that device is powered -
RUN (Yellow LED)
Regularly blinking indicates that the system is running, -
RDY (Green LED)
When light indicates that the system is ready and it manages the I/O modules according to the user program.
When it’s off it resets the output status on extension modules eventually connected to the system. -
DO0x (Red LEDs)
When light indicate that the corresponding digital output is activated.
I2 C™ is a trade mark of NXP Semiconductors
