LOC_TIME

Gerrie Slomp

My project is currently being commissioned, but now i've found the system time is't working anymore. I am using the function block LOC_TIME. While in simulation it works fine, but onto the CPU 315F-2 PN/DP it doesn't. Now I get errorcode -32623 and I couldn't figure out what it means. I am new to programming Siemens, so I am still figuring out some stuff. But if anyony can point me in the right direction, that would be helpfull.

Thanx in advance!

Description

The instruction reads the time-of-day status and time-of-day of the CPU and calculates the local time from this information. The instruction is only of practical use on CPUs with a time-of-day status. The instruction can be called in OBs of every priority class.
