Posted 14 Jul 2021 Hi Experts, I'm trying to connect and communicate between qj71c24n-r4 with e5cc temp controller via program-less modbus settings. (Digital temp Controller Communication Manual). and then monitor the values on the plc memory in a dialog box. (gxworks2) but failed to get some data's from e5cc temp. controller. may be i missed some connection or program from qj71c24n-r4 to extract the data's from e5cc temp controller. Can everybody give some advise. regards, Abs Share this post Link to post Share on other sites
Posted 14 Jul 2021 For modbus you can use the dedicated module QJ71MB91 than you only have to configure. If you use a regular C24 you can still comm via modbus but than wiou would have to use pre defined protocol function Share this post Link to post Share on other sites
Posted 14 Jul 2021 thanks for the advice sir, but right now i don't have qj71mn91 module. i have no choice but to use qj71c24n-r4 module. hoping for any solutions. Thanks, Share this post Link to post Share on other sites
Posted 23 Jul 2021 @Abs On QJ71C24N have "PreDefined Protocol" that supportModbus RTU communication then you can connect on CH2 but E5CC already have MC Protocol to connect with Mitsubishi PLC on page 167 - 178 of this manual below. https://assets.omron.eu/downloads/manual/en/v4/h175_e5_c_communications_manual_en.pdf Share this post Link to post Share on other sites
