Philip, Thank you for the support. I appreciate the reminder on the zero-crossing tech. It's the simple stuff like that which I sometimes neglect in pursuit of the complicated stuff. I'll have to drive the starters with ice cube relays. However, I won't use snubbers on the contacts of the ice cube ...

Thank you Philip, I've been looking through these devices and options this morning as well. I know best practice is to always put snubbers on all coils regardless. I'm trying to decide whether to install the snubbers, put in a slave ice cube relays and just let the ice cube relay contacts take the ...

Phil, Thank you for that information. In my panic, I missed the inrush/surge data on the 5069 output. Based upon what you shared, it looks like I'll be ok running one starter. Sadly, I have to report I found out the hard way and burned up one 5069 module because I neglected to recognize that a single ...

Looking to find the inrush/surge output capabilities on the 5069-OA16. The old 1771-OAD had some impressive surge capabilities which I'm converting from. The 5069 data sheet doesn't show anything whereas the 1771 does….. I want to drive a 509-AOD starter. The holding current on the starter is 1/4A ...

If I delete the instruction from the rung, perform the import, and select 'overwrite existing' during ...

I need some more help on a Modbus configuration. I haven't quite found an answer here on the forum and I don't live here much so pardon if this has been answered. I've been pulling data from Walchem modbus device to a Controllogix chassis L81E as a test. It works great after you folks gave me some ...

Got it working guys! Thank you. I failed to grasp the 0 / -1 addressing. I was not using even values and starting in the wrong place with incorrect length. Duh! (hand to forehead) I'm reading data now. I cannot believe that after all the data reads from various locations that I never had even ...

Need help from the community please with some Modbus communications problems I have a Walchem Intuition-9 Water Treatment Controller connected to an L81E v33. I'm using the v2.04 of the Modbus client AOI. The AOI connects to the controller but data is not being read into the 3xxx or 4xxx [tag]_data ...
