Serial Communications Ports

- Connector X10: to connect an

RS232/485 terminal (also for setup

purposes). Through this port, using

the Modbus protocol (master/slave)

or serial ASCII the PLC can connect

a fieldbus network;

- The RS232 cable must be shorter

than 15 m;

- Connector X11: RS485 port to

connect a fieldbus network using

the Modbus protocol (master/

slave) or serial ASCII;

- These two ports can be configured

using the DIP switches on the

right of the X10 connector;

- Isolation from other electronics:

1600 V.

ADespite the fact that the instrument has been designed to work in an

harsh and noisy environment, it is strongly recommended to follow

the following suggestions.

All the wiring must comply with the local regulations.

The supply wiring should be routed away from the power cables. Avoid to use

electromagnetic contactors, power relays and high power motors nearby.

Avoid power units nearby, especially if controlled in phase angle. Keep the low

level sensor input wires away from the power lines and the output cables.

Power lines and output cables must also be at 100 mm (min.) away from the CPU.

If this is not achievable, use shielded cables on the sensor input, with the shield

connected to earth.

AWarning!

Whenever a failure or a malfunction of the device may cause dan-

gerous situations for persons, things or animals, please remember

that the plant must be equipped with additional devices which will

guarantee safety.
