My company bought 2 PLCs Modicon Premium TSX H57 24M and ETYs 4103. My company want to make redundant system with that. The problem is I and my friend cannot configure hotstandby feature in that PLC. The software that we use is Unity Pro 4.0 XL.
We already follow basic manual but still no hope.
Our config are:2 PLCs already ON, with PLC sync-link and ETY sync-link connected each other with twisted pair crossover cable.
Networks config at Unity : IP address for ETY is 192.168.1.20 with subnet mask 255.255.255.0. YES: I/O scanning, NO: Global data, NO: address server. Other config: default.
I only use 1 module, ETY 4103 at slot 2 for both racks.
PLC config at Unity : Hot standby tab, rack.slot : 0.2; Command Register (%SW60), Standby on logic mismatch: offline. Other config: default.
ETY config at Unity : function : ETH TCP IP, net link : ETY4103_1 (name of my networks).
No error or warning when we build, analyze and rebuild all projects.
LED at PLC and ETY:
- RUN LED : Steady on at 1st PLC and blinking at 2nd PLC (500ms on and 2.5s off); Steady run at both ETYs
- STS LED : Steady on at both PLCs and ETYs
- ACT LED : Steady off at both PLCs
Can some1 please help us. Please tell us step by step configuration setting for hardware and software. Please tell us wheres our mistake so we can be better engineer
