Momentum M1E MSTR Function Block May Freeze Operation for 3-5 Minutes
Issue
The purpose of this Resolution is to inform users of Momentum M1E processors and 171CBB97030 Processor/4-Port Switches, of a potential problem with the TCP/IP MSTR function block.
If two or more TCP/IP MSTR function blocks are programmed and active at the same time, the function block may freeze its operation for 3-5 minutes but recover on its own without user intervention.
