IP 252 Expansion
When the IP 240 is used with the IP 252 closed-loop control module, control lines, which are only
implemented in the S5-115U programmable controller with a PS 7A/15A power supply, are re-
quired to coordinate direct data exchange between the modules.
The following explanations for this special mode therefore relate only to the S5-115U pro-
grammable controller.

Speed Measurement with the IP 252; DRS Controller Structure
The IP 252 high-speed closed-loop control module has eight separate control loops which can be
provided with actual values via their own analog inputs. Only one input is provided on the mo-
dule for connecting incremental encoders.
Inputs:
Digital
via IP 240
Incremental
on IP 252
Analog
on IP 252

Note
The IP 240 can only be connected to the IP 252
•
if an IP 252 with machine-readable product code 6ES5-3AA13, version A04 or
newer, is used,
•
if the IP 252 is equipped with an 6ES5 374-0AB11 submodule,
•
if the COM REG IP 252 software package beginning release A05 or COM REG
GRAPHIC IP 252 is used.
If you are using a CPU 944, you require MLFB 6ES5 944-7UA12 or -7UA22 or newer.
