Serial Gateway Overview
Section 6-1
Unifying to FINS Networks for Host Link Slave PLCs
■
Pre-Ver. 1.2 Units
Access to PLCs used as Host Link slaves from the PLC used as the Host Link
master by executing user-specified FINS commands is not supported. (The
PLC cannot be used as a Host Link master. Therefore, incorporation of a
communications sequence in the protocol macro is required.)
■
Unit Ver. 1.2 or Later
The Board/Unit’s Serial Gateway enables access to PLCs used as Host Link
slaves from devices on the network (personal computer, PT, and PLC’s CPU
Unit) using user-specified FINS commands. This enables use of the PLC as a
Host Link master while maintaining transparency on the network.
