hi everybody i have a network with 2 pieces cj1m and 2 pieces cp1l communicating with a ns15 monitor. everything is fine. i need to connect an ixt4a monitor in that network. my question is : do i have to make new routing tables or it is not neccessary? my routing table for cj1m and cp1l cpus are attached. if then i have to make new routing table so that the cj1m will be able to communicate ixt4a monitor, how am i going to do it for both monitors? Any help will be mostly valuable and appreciated. thanks

Hello everyone! I am not necessarily new to plc's but simply haven't had as much exposure to programming as I would like to have had over the years. I have a project that requires me to cycle three facility air compressors individually so that each one will aquire equal run time (approx) annually. Some requirements are: The start of the next one must overlap for a few minutes before the previous one shuts down, to avoid any loss of air pressure. Also, the system must run all three at once, upon power up, for a short period when the plant is first start up. The run times in this area are not critical either. I have a C200hs Omron PLC and I am using Cx Programmer to write the logic. So far I am using the one minute clock pulse to count down 5 or 6 hours between compressors and using timers to reset them. Does anyone think there is a way to use a shift register SFT to accomplish the same thing easier or? I am open to any suggestions as long as they're not vulgar. Lol. Thanks for any help!
