The connection between the IO controller and the basic submodule has been interrupted.
● The IO controller of the basic submodule is in STOP or POWER OFF state.he figure below shows the assignment of the address space for submodules 1 and 2 and
the value statusThe figure below shows the assignment of the address space for submodules 3 and 4 and
the value status.You will find information on the module-internal shared input/shared output (MSI/MSO)
function in the function manual PROFINET with STEP 7 V13 in the section Moduleinternal
shared input/shared output (MSI/MSO).The figure below shows the LED displays (status and error displays) of the
DQ 16x230VAC/2A ST.The following tables explain the meaning of the status and error displays. Corrective
measures for diagnostics alarms can be found in the section Diagnostics alarms (Page 23)Voltage missing or too low at backplane bus ? Switch on the CPU and/or the system power
supply modules.
? Verify that the U connectors are inserted.
? Check whether too many modules are inserted.

Digital output module DQ 16x230VAC/2A ST supports diagnostics interrupts.
Diagnostics interrupt
The module generates a diagnostic interrupt at the following event:
● No supply voltage L+
● Parameter assignment error
For more information on the error event, refer to the error OB with the "RALRM" instruction
(read additional interrupt info) and to the STEP 7 online helpA diagnostics alarm is output for each diagnostics event and the ERROR LED flashes on the
module. The diagnostics alarms can, for example, be read from the diagnostics buffer of the
CPU. You can evaluate the error codes with the user program.
If the module is operated distributed with PROFIBUS DP in an ET 200MP system, you have
the option to read out diagnostics data with the instruction RDREC or RD_REC using data
record 0 and 1. The structure of the data records is available on the in the "Manual
for interface module IM 155-5 DP ST (6E155-5BA00-0AB0)".The module cannot evaluate parameters
