Corrected from:
PLC Designer V4.0
Response of the new version:
If a new gateway is added in the 'Communication' tab of the 'Device' (Lenze Controller), the 'TCP/IP' driver is preselected in the 'Gateway' dialogue. Logging in is then possible without errors.
What happens?
When logging into a Lenze controller, the error message appears:
Communication error: #1cc
When does the behaviour occur?
If a new gateway is added in the 'Communication' tab of the 'Device' (Lenze controller) and the driver 'SharedMemory' is selected instead of 'TCP/IP' in the 'Gateway' dialogue, the error message described above will occur when logging into the controller.
Which products are
affected?
PLC Designer from V3.24
Short-term measures:
Open the context menu of the gateway and click on the menu command 'Edit Gateway'. In the 'Gateway' dialogue, select the setting 'TCP/IP' in the 'Driver' field and confirm the change with <OK>. You can then attach the Lenze controller to the gateway or search for it (button <Search network>).
Evaluation / recommendations:
As of PLC Designer V3.24, the driver 'SharedMemory' is preset by default when inserting a gateway for establishing a connection to the Lenze controller. If this setting is not changed to 'TCP/IP', an error message occurs when logging into the controller. In this case, no connection to the controller can be established and a project download is also not possible.
