I am using a expansion module TM172E28R on a TM172PDG42R controller with Machine Expert - HVAC software.
I have setup my controller and software exactly like in this video from Schneider: https://www.youtube.com/watch?v=pyJA31G2yQk&list=PLa7UGrWOTyjlgMo0lD4eVCV0zFQYxbLoa&index=7
I have setup up the controller as Can-Bus Master address 125 and the TM172E as slave address 1, also the dip switches are set (4-5-6 all off), the dip switcdh number one is on and is the EOL resistor.
I have also added a 120 Ohm resistor on the Can-Bus terminal from the M172P.
Somehow i cannot get the Master running with the slave running.
The sys variables for the CANbus communication is all zero.
I also have a input from the expansion module in my watch and its always false (voltmeter shows me 24VDC).
Is there anything what I can try else? Or is there a setting i need to set that is not in the manual?
The Firmware of TM172P is "596.10".
Any help is appreciated. Thank you.
Did you made a download all? Only in that case the CONNEC.PAR which is used for the communication will be downloaded. On the expansion is near the CAN Port a LED. Is this LED flashing? What is the status of sysCANopenNodeStauts?
