Detectability of an inserted HT 10 in the PLC
1. HW solution:
The X7 interface of the Basic PN connection module signals "HT 10 Present" at pin 1 for the
"active" connection module (see interfaces (Page 54)).
If the connection module is "inactive", this signal is not set.
This makes the "active" connection module detectable in the PLC by wiring pin 1 of all
connection modules with digital I/Os to PLC I/O modules in the PLC.
2. Permanently configured MCPs / HT 10s connected to one control:
If only permanently configured MCPs / HT 10s are present on a control, removing the MCPs
or HT 10s trips the PLC alarm "400260 Machine Control Panel failed".
Based on this an "active" or "inactive" MCP / HT 10 in the PLC can be detected.
The failure of an MCP / HT 10 is, however, only detected in the PLC if a max. of 2 MCPs / HT 10s
are permanently configured and there is no MCP switchover using FB9 (e.g. tripped when
operator focus is switched on the operator panel).
Note
Removing an HT 10 where the integrated machine control panel is active
Depending at which interface in the PLC (FB1: MCP1 or MCP2) the HT 10 is configured, the
transmission of machine control panel signals must be stopped before the HT 10 is removed.
This is possible as a direct access via data block DB7 (instance of the FB1).
To do this, set the corresponding interface signal to "true":
• 1st interface: DB7.DBX62.1 (MCP1Stop)
• 2nd interface: DB7.DBX62.2 (MCP2Stop)
If the machine control panel signals are not stopped, the message "400260 machine control
panel x failed" appears on the user interface:
Transmission of the machine control panel signals can be restarted after inserting the HT 10. To
do this, set e.g. the PLC interface signal DB7.DBX62.1 (MCP1Stop) to "false".
