Clear Local Statistics

Description

A clear local statistics operation clears the values from words 13 ... 22 in the statistics table of the local node. The operation is carried out in one cycle and does not require a master transaction path. To program an MBP_MSTR block to clear local statistics, use function code 4.

Network Implementation

A clear local statistics operation can be performed on Modbus Plus and TCP/IP Ethernet networks.
