    SUPER! Thank you very much Marcel!

    Hello all, I must show the alarms in the Alarm configuration on VISU. I have a structure like: arrA1 : ARRAY[1..50] OF FB1; And FB1 has a variable named bFault. I must therefore create one line for each array position, but I guess / hope I could use an array and automate the message to be shown. Currently I can create an alarm group, and add observation type digital, add each array position = TRUE and add the message... Can I make all the alarms of that array at once? Is that possible? and if it...

    Hello all, I'm making a project in whihc I have to show and edit a lot of values inside an array of structures: the structure has 3 reals inside: ST_DATA_ITEM { rFault : REAL := 0.0; rWarning : REAL := 0.0; rMinimum : REAL := 0.0; } And the array of structures: arrdataToShowAndModify : ARRAY[1..50] OF ST_DataItem; This makes a table (in the visualization) with 50 rows and 3 columns which is perfect. This said, how can I edit the values when touching them? I've been trying to find how to do it for...

    OK, solved... in TWinCAT you MUST put the variable you want to connect to any IO channel as %I / %Q or similar... it looks like in Codesys you MUST NOT. After reading the message slowly (good for me) I've been able to solve it and now I can directly assign the structure to the beginning of the Modbus channel. ^^Β‘

    Hello all, INTRODUCTION Started using Codesys this week, been using TWinCAT for years though. Programming is not an issue given my background, but the configuration part changes a little and I have a doubt about the ModbusTCPSlave I/O Mapping. I have to communicate the PLC (Modbus TCP master) to a small device (slave) which will send me 1 BYTEs, 1 WORDs, 1 BYTEs and 15 REALs (64 bytes or 32 words in total). I have put all those variables are inside a structure: TYPE ST_MODBUS_DATA_FROM_DEVICE_1 :...
