Communications: Smart Active Parts and Function Blocks
Overview
OMRON components that support CompoWay/F communications or Modbus-
RTU slave functionality (such as Temperature Controllers) can be easily
accessed from a CP1H CPU Unit equipped with an RS-422A/485 or RS-232C
Option Board using Smart Active Parts (SAPs) on an NS-series PT or using
function blocks in the ladder program in the CP1H CPU Unit.
The communications mode in the PLC Setup must be set to the Gateway
Mode to enable this functionality.
System Configuration
Note
Refer to OMRON’s Smart Library website for the most recent information on
using SAPs and function blocks.
Serial Gateway Function
When a FINS command is received, it is automatically converted to the proto-
col corresponding to the message and sent on the serial communications
path. Responses are also converted in the same way.
Note
Serial ports 1 and 2 on the CP1H CPU Unit can be used to convert to the fol-
lowing protocols.
