Hi all, was wondering if anyone could guide me on how to setup the PLC clock within my project. This is my first S7-300 and have learnt an awful lot, but am still a little hazy on some issues!
My system is acting as Modbus Master in one scenario to control a couple of compressors, and is a Modblus Slave to a Honeywell DCS system which is really only reading in Alarm/Status information. The only data they write to me is for the time synchronisation for Alarm Time stamping. I have mapped 6 DB addresses to receive the fields (Year/Month/Day....etc), and just need to assign them to the PLC and HMI clocks. There are 2 x 315-2DP CPU's (for Redundancy) and an MP370 (15"), any help appreciated.
