Station Detection Function
Station Detection Function
Refer to the Host Connection Manual (Multivendor Connection) for connection
methods.
The station detection function allows the NSH5 to read the box number
switches (4-bit switches) for removable boxes. Thus, when a removable box is
connected, the NSH5 is able to detect it.
By automatically displaying station screens, and by giving notification of which
station the PLC is currently in, the stations that can be operated can be lim-
ited. To ensure safety, other forms of operation are disabled.
The PT’s station detection function can be allocated any address in the inter-
nal memory, and the ON/OFF status can be monitored at the allocated
address.
To specify the address in internal memory that is to be allocated for the station
status monitor address, first select PT - System Setting in CX-Designer ver-
sion 6.5 or higher, and then click the NS Handy Terminal Tab. In the Station
Status Monitor Address Field, click the appropriate Set Button, and specify
the address that is to be allocated.
When removable boxes are used, the station numbers for the removable
boxes are acquired and notification is provided to one word in either $W or
$HW in PT memory. If function key status cannot be obtained due to a prob-
lem, such as a hardware error, or when a status error flag for an error, such as
a communications error, is generated, notification is provided to the same
word.
Bit allocations within the word is as follows:
Any number from 1 to 15 can be set for a station box. For station number
switches, wire station ID line signals S1 to S4 in relation to the station num-
bers as shown in the following table.
