[concept 2.2 SR2]

!st of all i do not know Concept at all. But can you open other projects? This error looks to me like a concept error rather than the project file...There are default paths normally set for software to open certain files and if that path or file doesnt exist you get errors similar to this

[How to show multiple values in a StringDisplay?]

Will your string have values in on the plc or do you need to type in messages on Vijeo designer?

[How to show multiple values in a StringDisplay?]

Sorry the above method can only give 255 messages in one text resource. Let me check for another solution

[How to show multiple values in a StringDisplay?]

Choose a message display block. As shown in picture. You need to create a text and colour resource (under resources) 

Then in the message display properties you need to select the colour and text resource you created and use the integer value as your variable in the message display block. No arrays needed. Just type your messages in the text resource next to the value of the integer

[M241 Modicon Modbus TCP Slave input register reading problem]

I normally write the inputs and outputs to %MW or %M. Then you shouldnt have a problem. Not all modbus softwares allow all the modbus functions. But most should allow reading x3 and x4 which will be %mw and %m

Hi Tony

What driver are you using?I suspect its modbus. Open the device (plc) comms settings in the IO manager  in Vijeo Designer. Change the double word order to the other option

[Control Transformers in a Control Panel]

We often supply cabinets where our supply is prone for spikes. Using a control transformer reduces the damage that can be caused to the control side ( power supply or coil etc side). That is our main reason for installing them. If history is a yard stick then I wouldnt go without them in a 3 phase to single phase or 24vdc control cabinet. 

Even when supplied by single phase. Might be an overkill but doing things proper results in less problems. Often don't know the state of customers electical supply until there is a fault in your cabinet

[send only hex number via rs232 serial line 1 M241]

try and just use the send function block and once done the receive....just a thought. Also you can convert dec to hex, hex to string etc just as you like in the plc. Its all binary in the end. Length of message might be an issue but unless knowing what device or model you are using I cannot be sure. 

Ps. the physical interface is the most important. if that isnt right you will not get any communication.
