hi there,
i m today in a position where i require to convert protocol.
the reason is i m working on a project where one device talks in modbus and other PLC has its own proprietery protocol,and i have to communicate them.
the PLC manufacturer has disclosed the protocol and now i can recieve and send data to that PLC with proprietery PROTOCOL.
What i m doing is i m using one computer in between these two deivces and to its COM1 port there is MODBUS master decive attached and to its COM2 port i have attached the PROPRITARY PLC.
now today i m in a position to
1:send n recieve frames from PC (computer) to Propritary PLC
2:and using modsim32 on Computer i have checked the communication with MODBUS master device.it is successfull
now how to write the code so that the data received from the Propritary PLCs registers are sent to modbus master device who is querying for the same???/
for this purpose out of MODBUS RTU OR MODBUS ASCII which will be more advantageous?
sorrry for my awful english, hope everyone will understand it.
thank u
