Clear Remote Statistics
Description A clear remote statistics operation clears remote-node values from words 13 ... 22
in the statistics table of the local node. It uses a master transaction path and may
require several cycles to complete. To program an MBP_MSTR block to perform a
clear remote statistics operation, use function code 8 (see Operational Function
Codes, p. 151).
Network
Implementation
A clear remote statistics operation can be performed on Modbus Plus and TCP/IP
