PLC S7-300, CPU Specifications CPU 312 IFM to CPU 318-2 DP
A5E00111190-01
Technical Specifications of the Digital Outputs of the CPU 314IFM
Remarks
When the supply voltage is switched on a pulse occurs on the digital outputs! This
can be 50 ms long within the permissible output current range. You must not,
therefore, use the digital outputs to trigger high-speed counters.
