Example of EPI Calculation
The following network configuration is used for an example of calculating the EPI. The baud rate is 500 Kbit/s.
The NE1A-SCPU01 sets safety connections between four DST1-ID12SL-1 Input Terminals and four DST1-
MD16SL-1 I/O Terminals. The default set values are used for all the safety connections, and the EPI is 10 ms.
Also, the CJ1W-DRM21 sets the standard connections between four DRT2-ID16 Input Terminals and four
DRT2-OD16 Output Terminals. The default set values are used, and the communications cycle of the CJ1W-
DRM21 is automatically set but it attempts to operate at a cycle time of about 3.2 ms.
