( Page 45, Section 6.4)
Stops the data transfer between the link devices (cyclic data from the master station) of the head module
and the devices in the head module. (Stops the transfer while performing cyclic transmission with the
master station, and turns the output off.)
By stopping the data transfer, the input/output of the module connected to the head module are not sent to
the master or local station. The STOP switch is used to perform a debug operation between modules
connected to the head module and external devices.
The following shows an example of a debug method with external devices using the STOP switch.

(2) Data transfer is stopped between the link devices of the head module and the devices in the head
module, and the devices are separated from the master station control.
(3) Perform an input/output test between the module connected to the head module and the external
device. Since the data transfer is stopped, the input/output status data are not sent to the master or
local station.
(4) Upon completion of the test, data are written to the head module and the system operation starts.
Starts the data transfer between the link devices (cyclic data from the master station) of the head module
and the devices in the head module.
