4 Communication settings and guide of HMI connecting with controller
NOTE: Dual redundant parameters configuration of S7-400 Ethernet communication
16.0 The station No. is composed of two parts: track No. and slot No., and station No. is a byte, the track
No. is the high 4 bits, and the slot No. is the low 4 bits. For example, the station No. is 0x03 in hex,
that is to say, the track No. is 0 and CPU slot No. is 3.
17.0 Protocol timeout 1 stands for IP address of redundancy PLC. For example, if the IP address is
192.168.100.240, corresponding to the hex value 0xC0A864F8, then transfer this value to decimal, it is
3232261368.
18.0 Protocol timeout 2 stands for tack No. and Slot No. of redundant PLC, for example, if the Protocol
timeout 2 is 19, corresponding to the 0x13 in hex, that is to say the track No. is 1 and slot No. is 3.
19.0 When configuring PLC in HMI program, just need to configure one PLC but not two.
