external equipment via configuration logic circuits
The Multiple Command function block, available in REC 561, has 16 out-
puts combined in one block, which can be controlled from the operator
station, that is, the whole block is sent at the same time from the operator
station. One common name, with a maximum of 19 characters for the
block, is set from the configuration tool CAP 531.
The output signals, here CMxx-OUT1 to CMxx-OUT16, are then availa-
ble for configuration to built-in functions or via the configuration logic
circuits to the binary outputs of the terminal.
The normal way to control circuit breakers, disconnectors, and earthing
switches with full functionality from the operator station is to connect the
command function via the apparatus control function (see "Apparatus
Control", 1MRK 580 150-XEN).
This Multiple Command function block can also be used to receive infor-
mation over the LON bus from other REC 561 control terminals . The
most common use is to transfer interlocking information between differ-
ent bays. That can be performed by an Event function block as the send
block and with a Multiple Command function block as the receive block.
Detailed information of how to transfer the interlocking information is in
"Apparatus Control", 1MRK 580 150-XEN. The configuration for the
communication between control terminals is made by the LON Network
Tool.
The MODE input is set to Steady at communication between control ter-
minals and then the data are mapped between the terminals.
The command function also has a supervision function, which sets the
output VALID to 0 if the block did not receive data within an INTERVAL
time, that could be set. This function is applicable only during communi-
cation between control terminals over the LON bus. The INTERVAL
