Put %f in the "text" field and rValue in the "Text variable" field. You could also have a look at the possible placeholders: https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_placeholder_with_formatting_sequence_in_a_string.html

I have come across this. The only way i could get it to work would be to define a word that is also the same address as the Bools. eg %MX600.0 through to %MX600.15 would be individually defined in the variables and them have another variable word defined at %MW300. You still need to break out the word in what ever program you are using to read/write the OPCUA tags.

The error often occurs during TCP read/write operations Smash Karts or after closing and reconnecting a TCP connection, leading to unreliable communication or the need for a controller reset.

Post by kurtk on Modbus TCP Server

ditto I'm just getting my codesys wheels on and the modbus stuff is confusing. I am re-platforming an existing PLC application On that platform one could simply tag variables to register numbers and the whole shooting match could be accessed via modbus and typically holding registers and input registers were treated the same way... On codesys I see there is a modbus TCP server Device I/O mapping tab and a Modbus TCP server IEC objects tab I get the sense that one can configure the serving of variables both/either way but am unclear about the optimum/necessary path. Apparently in the IEC Objects tab one can "ADD" something or other - presumeably channels. I have created a preliminary function block but the Select Function Block window shows nothing to select WTH ? I exported the Device mapping and was surprised to see the entire Device IO map - complete with all the bit-mapped holding/input registers!! WTH!!?? Bit-mapped words are strictly a nichey special purpose application. I am targetting making a couple hundred variables available which would turn into hundreds of pages of IO/mapping Is the FUnction Block IEC objects thingy an alternative to that ? I notice that CODESYS shows the tags which the PLC used to specify the register address... are tags used in CODESYS for any specific hard-core purpose ?
