  1. Hi Folks, I'm new to this forum and have an issue for which I would like to pick your collective brains! I have 4 x SLC5/05 CPUs which are connected together using ethernet. The 4 CPUs and my laptop are all connected to a switch which is operating at 10M. All CPUs can be communicated with via RS Linx with no probs. These PLC control turbo blowers which are in a group and they designate their Master Blower based on the lowest hours run etc. This means that they all run the same code and read from each other's registers to ensure that if another blower was to assume Master then it's code would be up to date. The CPUs all read from each other via a MSG command. Before downloading the code to each CPU I have entered the IP address into the relevant box in the MSG config screen. Once downloaded and running all MSG commands return a comms error "Connection refused by host". The IP address is only shown as either 19x or 19 on the MSG config screen which I assume must be causing the comms error as this is invalid. If I then save the code online I have to re-enter all 4 IP addresses before RS Logix 500 will permit it to be downloaded once again. Could anyone shed any light on this as I am at loss and have never seen this before. The IP addresses are as follows: Laptop 192.168.1.1 CPU 1 192.168.1.2 CPU 2 192.168.1.3 CPU 3 192.168.1.4 CPU 4 192.168.1.5 All subnet masks are set 255.255.255.0 I've attached an example of how I am enabling the MSG instruction and also the config screen. Sorry for the War & Peace but I am at a loss - HELP!!!!!!!!! Gavin
