Configuring and assigning parameters for option handling
Introduction
Configure option handling as described below.
Procedure
1.
Drag a PM E-DC24 power module (6ES7148-4CA00-0AA0) with one of the following
entries into the configuration table:
–
O (option handling)
Note
Enter the power module that ends in O only once in the ET 200S configuration!
2.
Assign parameters to the interface module as follows:
Interface module
Parameters
Setting
Description
IM154-1 DP
(6ES7154-1AA01-0AB0
or higher)
IM 154-2 DP High
Feature
(6ES7-154-2AA01-0AB0
or higher)
Option handling
Enable
Option handling is
enabled for the entire
ET 200pro.
Note
If "Operate with set < > actual installation" is disabled during parameterization, the
ET 200pro will not start up if a module is missing or if an incorrect module is inserted. If an
incorrect module is inserted, the ET 200pro will start up but the I/O will not be enabled.
The diagnostic "No module" or "Incorrect module" is signaled.
If the IM154-1/2 does not start up in this state, the SF LED lights up on the IM154-1/2 and on
the deactivated electronic module of the ET 200pro.
Note
With option handling, incorrect assembly of the control interface can result in a signal in
which too many modules with a slot number greater than 17 are plugged from the
perspective of the interface module. Since there is only room for 17 modules in the
diagnostic frame (module status), the most significant bit is set in the "Identifier-related
diagnostics" in this case. This produces the following results:
•
The SF LED on the IM lights up
•
Bit 3 in status byte 1 of the diagnostic frame is set (external diagnostics available)
•
The "Slot 18 faulty" error message is indicated in STEP 7.
