Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Hi all, I want to know if someone has an idea of how I can write on value change in Modbus Codesys. I have a Wago PLC and I was used to work with E-cockpit which it was quite easy to do that without the necessity to trigger any value when there was a change in the variable ( I will put how easy is ). how you can see just changing the trigger in "On value Change" will do that channel writing automatically when It detects a change in those arrays. On the other hand, in Codesys if I enable the rising edge in Codesys It ask me to put a bool variable and if triggers is going to write that value. That is making me that I have to create a function or a logic to detect the change, the problem I have is that doing that is very tedious. I first approach I got it was to create a Function who returns a bool when the value change, but I tried to keep the old value but what is happening is that in Functions all the data is erased every cycle so I can not keep any Old value. so in the Main program the trigger is going to be TRUE all the time due, the old value is cero every cycle. The second approach I got it was using a function Block (POU_1) and it works but I dont want to instance that function for every Channel or value that I want to check if the value change, Basically if I have 200 values to write trhough modbus I have to create 200 instances of that function which I think it is not practicall at all. It should be a better way to implement this as e-Cockpit from Wago Does. However, I haven't been able to know how.

Post by installwhat on Initialization of POUs (FB_Init) ^{CODESYS Forge talk (Post)}
Hi I was wondering if there's a pattern I can employ to acheive what you're doing but with a "reference to" and also allowing for online changes? Someone told me that the new beckhoff keeps references safe during online changes but all the documentation I've found suggests that's not the case. The easiest thing is to use fb_init for normal vars and pointers and references can be added in the function body every cycle and this allows for method calls after so far as I can tell.

Post by eschwellinger on RS485 CAN HAT to Cosesys ^{CODESYS Forge talk (Post)}
Hi if you add in (ttyAMA0 should fit to your HAT's device [SysCom] Linux.Devicefile.1=/dev/ttyAMA0 to /etc/CODESYSControl_Usr.cfg since 4.12.0.0 version /etc/codesyscontrol/CODESYSControl_Usr.cfg then access in CODESYS with Com1 should do it. Keep in mind that only adapters work (for RS485) which do determine the send/receive direction in hardware

Post by anderson on function block output ^{CODESYS Forge talk (Post)}
so it is not possible for me to use the function blocks and through them I can select the digital outputs of the PLC so that pulses and direction are output, or some function block that does this reading and in it I can program the pulse and direction outputs for the drive?

Post by timvh on CAN Open Manager - varible of SYNC ^{CODESYS Forge talk (Post)}
You can enable "Sync Producing" in the configuration of the CANopen Manager. Then this manager will send a SYNC message every interval you set. Depending on your PDO configuration, the CAN nodes can send a PDO on every Sync (cyclic-synchronous). If this is not possible, then as alternative you can send a low level CAN message with COB-ID 16#80.
