Performance Features of the CP 541
The significant performance features of the CP 541 are described in the fol-
lowing.
You can use the CP 541 for the following fields of application:
Subsequent networking of installed programmable controllers of the SI-
MATIC S5 family
Substitute for SINEC L1
For connecting failsafe programmable controllers of the SIMATIC S5
family via SINEC L2
You can establish the following communication links via the CP 541:
PLC-PLC link
Broadcast
DP link for operating programmable controllers of the SIMATIC S5 fam-
ily as a DP slave with any DP master in SIMATIC S5 and S7/M7 or with
any DP master from another manufacturer.
In contrast to other DP slaves, the CP 541 exhibits a minimum cycle time
of 10 ms. It supports PROFIBUS profiles DP/FMS and User Defined at
transmission rates of up to 1.5 Mbps and PROFIBUS-DP or DP for
IM 308-B at up to 187.5 Kbps.
Safety-related data traffic between failsafe programmable controllers of
the SIMATIC S5 family
The communication concept has been tested for freedom from reaction of
the safety-related SINEC L1 communications between failsafe program-
mable controllers. The CP 541 is a non-safety-related module and can
therefore be operated without a special test. However, the general condi-
tions for special testing of the programmable controller must be observed.
