FINS Ethernet Master / Slave Solution

---

Drop in code for Single Master and up to 30 Slave PLCs on FINS Ethernet.

The Master PLC can be a CP1L-E, CJ2M, CJ2H, CS1, or any PLC capable of sending FINS commands.

Originally designed to share data across a network of CP1L-E PLCs.

Each PLC shares 100 words in each direction with the master PLC.

The reads can be setup to read as fast as possible, or at a given interval.

The writes can be change of state (COS) driven, as fast as possible, or at a given interval.

.pdf manual included.

Dear PMCR, first of all thank you for your great Sample Code, it really is awesome the way it works and really adds value to the FINS only CP1L-E PLCs. However I am using two CP1L-EL20 Units and ran into a strange issue that looks like a bug, making ordinary 100.xx Coils on the Master PLC unuasable. On the Master PLC: If you set a Coil 100.xx active at program start it will get stuck when you reset it by any condition made in the very rung. Reason is the last entry in the Program Communications_do_not_change, Section Read Data, if you deactivate (P_OFF) rung Nr. 3 (MOV FIFOED_Read_Stack_PLC_Number 100) things will work just fine. Can you please check your code, my knowledge so far is too limited to actually understand what this rung does. However I have kind of a feeling that it is just a mix up of values . It took me almost two days to find out that the problem lied within a do_not_change program so I thought it is worth sharing . Again thanks for your great work so far. Can you please let me know what I have gotten into? BR Martin

Hi PMCR...I download this code last night, but it says that my current CX cannot open the program. I am running CX 9.32. Does this have any bearing on why the code will not open? Cheers!
