Information on configuration and operation
3
● The blocks in the library have been designed exclusively for S7-400 automation systems.
● ET 200iS, ET 200X and DP field devices cannot be operated on an H system downstream
from a Y link with PCS 7 standard blocks.
● An ET 200S (IM 151-1 High Feature) and a diagnostics repeater can be supported
downstream from a Y-link only as a DP V0 slave, this must however be configured as DPV1.
● You are not permitted to set the minimum cycle time of OB1 to a value other than "0".
With the CPU 410 PA SMART, the minimum scan cycle time of OB1 is permanently set to
200ms.
● One-sided distributed I/Os are not supported in PCS 7.
● The adjustable options "Status of supply voltage L+" and "Status of feedback voltage" are
not supported for ET 200SP server modules. If these options are not selected, a diagnostics
module is created for the server module. If these options are selected, a warning is issued
when compiling with the module driver generation and no diagnostics module is installed.
The functionality of these options cannot be used with channel blocks.
● Value status is only supported for ET 200SP HA modules.
● The user-defined data types (UDT) of 1 to 50 and 200 to 299 are reserved for PCS 7
Advanced Process Library and PCS 7 Basis Library .
