8.2.4 Time stamping outside of S7-400
8.2.4.1 Prerequisites
With the interface module IM 153-2Bxx1, time stamping is also possible outside of an S7-400
automation system.
The above principles and rules apply - if complied with, precisions of up to 1 ms can be
achieved.
Synchronization interval for the time: 10 s
Demands on the ET 200M and DP master
ET 200M:
• IM 153-2 as of order number 6ES7153-2Bxx1-0XB0
• suitable DI modules
• IM 153-2 must be configured via GSD rev. 5 (e.g. enabling of interrupts)
• for IM 153-2 the DPV1 mode must be activated
• Synchronization interval in accordance with the setting on the clock master
DP master:
• must fulfill requirements in accordance with DPV1
• must be able to process interrupts
