I'm trying to set up connection between PC and Festo motor controller (with Ethernet/IP module).
PC: Win x86 LV2012SP1f4 + NI Ethernet/IP 1.3 driver
Festo Motor Driver: SMMP-AS-C5-3A-M3 with CAMC-F-EP ethernet/ip module included
I'm able to read all classes/instance/attributes that fest offers but i have problem with assembly.
Via assembly instance 101 i suppose to read the 16B data frame from controller and via assembly instance 100 i suppose to write the 16B data frame to controller. That works without error. The size is return correctly as 16B if i read attribute 4.
But the data inside does not change at all, the read data does not correspond to the actual state of the controller and written data has no impact on the controller as well.
I Attached my simple Vi to communicate with the controller:
Niether NI tech support niether Festo support is not able to help me. NI thinks this is controller issue, Festo thinks this is labview driver issue since the communication is working with PLCs like AllenBradley. I stucked in between.
Anyone know what the reason may be? Thanks for any kind of help
