6 DEDICATED INSTRUCTIONS
POINT
(1) Remote RUN/STOP becomes valid when the RUN/STOP key switch of the
target station's Q/QnACPU is "RUN."
(2) Remote RUN/STOP cannot be executed when the system protection is activated
on the target station's Q/QnACPU (the system protect switch is on).
(3) When other station has executed a remote STOP/PAUSE operation on the target
station, the RUN request cannot be executed if the mode of (S2) + 2 is "Do not
force execution (0001
H
)."
(4) If the Q/QnACPU of the target station for which a remote RUN/STOP operation
has been executed is reset, the information of the remote RUN/STOP is erased.
(5) The clear mode ((S2) + 3) designates how the clear (initialization) processing of
the Q/QnACPU device memory should be performed when the Q/QnACPU starts
performing calculations after a remote RUN request has been issued to it.
The Q/QnACPU executes the designated clear and then goes into the RUN status
according to the parameter settings (PLC file setting Device initial value).
Functions
(1) This instruction sends the request data designated by (S2) of the local station to
the station connected to an MELSECNET/H, MELSECNET/10 or Ethernet
network system, which is designated with the network number and station number
in the control data, and makes a service request.
When the request to the target station is completed, the completion device
designated with (D2) turns on

REQ
(2) Device data can be sent from stations connected to either the MELSECNET/H,
MELSECNET/10 or Ethernet networks having the designated numbers, in addition
to stations connected to the local station's network.
(3) The data link instruction and instructions for the Ethernet network system cannot
be executed at two or more locations for the same channel.
If the execution conditions are met at two or more locations at the same time,
instructions to be executed later have to wait until the channel becomes available
because handshaking is automatically performed at the execution of the first
instruction.
