Removal/Insertion Interrupt with S7/M7-DP Master or DPV1 Master

If you use the ET 200M with ”module change during operation” on an S7/M7-DP

master or a DPV1 master, the system behaves as follows:

 When a module is removed, the IM 153-x reports a module removal interrupt on

the DP master that executes OB 83. You program the desired response to the

module removal event in OB 83.

In the case of I/O access, OB 122 (I/O access error) is called in the DP master.

 If you insert a module that corresponds to the configuration, the IM 153-x

reports a module insertion interrupt to the DP master (OB 83 call with

diagnostics buffer entry) and assigns parameters to the module in keeping with

the stored configuration.

 If you insert a module in an unconfigured slot, the IM 153-x doesn’t report a

module insertion interrupt.

 If you insert a different module than configured:

– the IM 153-x reports a module insertion interrupt to the DP master (OB 83

call with diagnostics buffer entry); but it ignores this unconfigured module.

– The module diagnosis is stopped, and you can read out the slot in which the

wrong module is inserted (see Section 6.4.5).

– The SF LED shows the error.

Note: Inserting or removing a DM 370 dummy module does not trigger an insertion

or removal interrupt.

Warning

Problems during removal and insertion are tolerated for up to 1 second.

This means that the output values will not change within the tolerance time in the

event of such a problem occurring.
