Replacing the ET 200S pulse generator and positioning modules
This information is relevant to the "2 Pulse" pulse generator modules (6ES7 138-4DD00-
0AB0) and "1 Step 5V" positioning modules (6ES7 138-4DC00-0AB0) from a project which
was created with TIA Portal V11.0. When replacing these modules from the TIA Portal V11.0
with a new version of these modules, the parameter settings are reset to the default values.
This is the case with one of the following procedures:
● Replacting the pulse generator module 6ES7 138-4DD00-0AB0 or the positioning module
6ES7 138-4DC00-0AB0 with their successor modules 6ES7 138-4DD01-0AB0 or 6ES7
138-4DC01-0AB0 by means of a device replacement.
● Updating the module version using the appropriate button in the device properties in the
Inspector window.
2.2.5 Setting flow control for CM 1241 (RS232)

Values for XON and XOFF
If flow control is enabled for the CM 1241 (RS-232) communications module and set to
"XON/XOFF", you can enter identical values for the XON and XOFF characters. From a
technical point of view, however, this configuration is impractical. You should therefore use
different values for XON and XOFF.
