Restrictions on the Use of S7-300 Standard SMs
The restrictions for fault-tolerant systems are applicable to the use of S7-300 standard SMs
in S7 F/FH Systems (see
For the restrictions for S7-300 standard SMs in safety mode of F-SMs, refer to the
Automation System S7-300 Fail-safe Signal Modules
ET 200S Fail-safe Electronic Modules
The following fail-safe electronic modules (F-modules) are available in ET 200S:
• PM-E F pm 24 VDC PROFIsafe power module with 2 additional fail-safe digital outputs
• PM-E F pp 24 VDC PROFIsafe power module
• PM-D F 24 VDC PROFIsafe power module
• 4/8 F-DO 24 VDC PROFIsafe digital electronic module
• 4 F-DO 24 VDC/2 A PROFIsafe digital electronic module
F-modules can not be used with standard CPUs in standard applications.
Interface Modules for ET 200S with Fail-safe Modules
One interface module is required for each ET 200S. The F-system determines which
interface module can be used:
Table 1-4
Interface Module
IM 151-1 HIGH
FEATURE
IM 151-7 F-CPU
IM 151-3 PN HIGH
FEATURE
Note
Unlike IM 151-1 HIGH FEATURE, for example, the IM 151-7 F-CPU is an intelligent
preprocessing device (intelligent DP slave) and can also be used as a DP master. An IM
151-7 F/CPU can therefore exercise full and, if necessary, independent control over a
technological functional unit and can be used as a stand-alone CPU or F-CPU. The IM 151-7
F-CPU represents an addition to the line of F-CPUs for S7 Distributed Safety.
