Appreciate any help in advance.
Connected just fine to a Hollysys LM3106 PLC Processor via ethernet to serial convertor. Am able to read coils just fine from the unit.
Have 3 memory locations in the PLC that I am attempting to read (this is not a finished PLC program, but rather a proof of concept program).
The memory locations have to start at MX100 as MX0-MX99 are reserved for system diagnostics.
If I go online via the plc supplied programming interface, I can see those address update to the correct value as the program cycles (couple of timers cycling each other).
Page 182 of this manual describes holding register addressing. (sorry for not being able to link the specific excerpt) - automationlasso-store.com/me … l_v1.0.pdf
I have tried every iteration of addressing direct in Ignition (using direct addressing such as [Test Unit]51.HR3000.5 and [Test Unit]51.HR100.5, [Test Unit]51.HR3801 etc)
I am trying to read the following addresses
Any thoughts would be so very much appreciated. Once I get it figured out for one address, I can get the rest going.
