The 2573-MOD provides support for communicating with serial and Modbus

plant floor devices such as modems, bar code readers, scales, displays,

printers, and other PLCs.

Features

• Provides 4 serial ports, each providing RS-422. RS-485 and RS-232 electrical

interfaces. All ports operate concurrently and independently.

• Enables the PLC to act as a master or slave for devices which use Modbus

RTU or ASCII protocols

• Task Code Master support allows the local PLC to access memory in other

2500 Series® or Simatic® 505 PLCs
