[Disposal Precautions]
!
DANGER
• Please refer to the manual for each station concerning the operating status of each station when
communications errors occur in the station. There is danger of accidents due to wrong outputs
or wrong operations.
• When connecting a peripheral device to the CPU module or performing control of a
programmable controller which is being run through a BASIC program, configure an interlock
circuit in the sequence program so that the system overall is operating on the safe side at all
times. Also before exercising other control (program change, operating status change (status
control)) on the running programmable controller, read the manual carefully and fully confirm
safety. Especially for the above control on the remote programmable controller from, an
immediate action may not be taken for programmable controller trouble due to a data
communication fault. In addition to configuring up the interlock circuit in the sequence program,
corrective and other actions to be taken as a system for the occurrence of a data
communication fault should be predetermined between and programmable controller CPU.
• Do not write data to the "System Area" in the intelligent function module's buffer memory.
Also, do not turn ON the "Use Prohibited" output signals among the output signals from the
programmable controller CPU to the intelligent function module.
If data are written to the "System Area" or output in response to "Use Prohibited" signals, there
is danger that the programmable controller system will malfunction.
