Operating mode DI
3.2 Parameters/address space
Digital input module DI 8x24VDC HS (6ES7131‑6BF00‑0DA0)
16 Manual, 03/2015, A5E35243810-AA
Parameters/address space
3.2.1
High-speed inputs
Function
In operating mode DI, use all eight channels as digital high-speed inputs. High-speed inputs
make sense when rapid reactions to input signals are needed (reaction time < 2 ms).
Low reaction times require a cycle time of less than 750 µs.
The effective range of the parameters depends on the type of configuration. The following
configurations are possible:
● Central operation with an S7-1500 CPU
● Distributed operation on PROFINET IO in an ET 200SP system
● Distributed operation on PROFIBUS DP in an ET 200SP system
In addition to configuration via the configuration software, you can also configure parameters
in RUN mode (dynamic) via the user program. When assigning parameters in the user
program, use the "WRREC" instruction to transfer the parameters to the module using the
data records; refer to the section Parameter assignment and structure of parameter data
record for DI operating mode (Page 66).
