this is for a "master" system, if you will, that would be used in different facilities with multiple pieces of equipment. each piece of equipment would have the same programming in it but different facilities would have different IP addressing.
The "master" PLC will also have the same programming in it from facility to facility.
The master will comm with all other equipment via Ethernet and MSG instructions. There are several MSG instructions per piece of equipment.
Each piece of equipment is programmed to allow the operator to change the individual IP addresses on each piece of equipment including the master.
Problem:
need to allow operators and service personnel to enter a desired IP address into 4 DINTs (one for each octet) (via HMI... no problem there)of the set IP addresses in each piece of equipment so that I can set the IP path in MSG instructions.
I need to find a way to combine the 4 separate octets for each IP address, subnet, gateway in 4 different DINTs and combine each one into an IP string or a HEX then using SSV write to each message the new IP path.
if anyone has done this before im all ears....
