Undefined_Protocol

@Gambit, Yes. I will try it again. Thank you sir.

@Gambit, yes, that is what the tool looks like, and then the question of the multiple protocol execution still clouds my mind. if they said that in the CPTRCL instruction you can execute up to 8 protocols, can the simultaneously executed protocols be of different frames?   Thank you for the response sir.

@JRoss, I think I must try for more research before confirming the information, because if the tool doesn't allow the multiple protocol execution on 1 interface, they should've told that in the manual, that is why I am confirming stuff with you guys. Anyways, thank you for the opinion sir.

@Gambit, Thank you for responding!   So to clearly state the set-up, for example, a plc with the serial module is connected to five vfds on FREQROL communications and two power meters communicating on MODBUS can seamlessly send and recieve data through a three wire bus (TX, RX, SG)? Thank you.

Mr. @Gambit, Thank you for the response to my query. Actually I know the simple communications very well, yet when the communication involves the new FX5plc, which the simple communications function do not support, we have to use the socket communications. Anyways, I appreciate your efforts. 

Mr @Clear.Mind,   You provided the solution very clearly to me. I already tried to adapt the solution and the workarounds of the function. Thank you!

Hello guys! Do you guys know if it is possible that the predefined protocol function of the RS485 module of the L/Q series can execute different protocols (MODBUS, FREQROL) using only a single cable of a three wire branch? I would appreciate any help that you can relay to me. Thanks.

Guys! I will appreciate any help on this.   This is my current situation: I wanted to read data registers from my FX5U PLC to the L02CPU using Ethernet communication. I am new to fixed buffer communications and socket communications , so can you guys lend me a hand in dealing with this study? thank you very much guys. Listed below are the hardware:   1. FX5U-32MR/ES 2. L02CPU 3. 1 meter CAT5E LAN cable (straight connection) 4. IQ Works 2 (GX Works2 and GX Works 3)   Can you provide me with a sample program and system architecture on this? I would appreciate the help guys.    

Hello brother,     Before I can help, may I ask if you know about the predefined protocol function in GX Works 2?
