6. P1 INSTALLATION
Figure 16 P1 Module - Front Panel
The P1 module provides connectivity between the Link system and a PLC.
Communications between the P1 module and the PLC can be done using
one of the available ports: the RS232 serial port, the RS485 serial port or,
for Modbus systems, the Ethernet port. Only one of the three ports can be
assigned for PLC communications at a time. The Ethernet port is
available for monitoring the status of the Link system regardless of which
port is selected for PLC communications.
Protocols used by the module are:

Modbus slave

Modbus master

Modbus TCP/IP slave

Modbus TCP/IP master

Allen-Bradley DF1 Point-to-Point PLC5 master

Allen-Bradley DF1 Point-to-Point SLC-500 master.
