Module 9007 Diagnostic information of the PL
Module 9007 can ascertain diagnostic information on the PL 4xxB. To save
computing time, refrain from continuously calling this module.
Call:
PS B/W/D/K <Number of the logical PL>
PS B/W/D/K <Number of the information>
0: Readiness
1: Supply voltage
Bit 0: Logic voltages 24 V and 5 V
Bits 1 to 4: 24 V for X11 to X14
Bit 5: 24 V for analog inputs
2: Analog inputs used
3: Total number of PLs on this LE
4: Further PLs on this PL?
5: PL is a PL 410 B
CM 9007
PL B/W/D/K <Diagnostic information>

The current conditions of the switching inputs and outputs are available for
you in PLC addresses
(See "Mounting and Electrical Installation" on page 3 – 5).
For the current states of the inputs/outputs of the PLC:
7 7 7 7 Read all inputs with Module 9002.
7 7 7 7
Or only certain inputs with Module 9008.
7 7 7 7 Update all outputs with Module 9005.
7 7 7 7 Or only certain outputs with Module 9009.
