Modbus, AC800M, PM860.

Hello, you answered my question regarding MODBUS RTU communication with ac800m pm860 controller with some pictures. I am having trouble viewing the pictures because of the resolution, do you have those pictures with more zoom or higher resolution?

Here is the link http://www402.abbext.com/ViewQuestion...

Best regards

Very important is also following:

In CP853 folder (or com parameters folder) in CB - Set Poll Time = 0 in hardware configuration, settings for Modbus. This cancel waiting of FC8 respond from the slave, which is not supported by all vendors, and gives valid status of MBConnect immediatelly.
