[Design Precautions]
• Do not write data into the "system area" of the buffer memory of intelligent function modules.
Also, do not use any "use prohibited" signals as an output signal to an intelligent function
module from the CPU module.
Writing data into the "system area" or outputting a signal for " use prohibited" may cause a
programmable controller system malfunction.
[Design Precautions]
• Do not install the control lines or communication cables together with the main circuit lines or
power cables.
Keep a distance of 100mm between them.
Failure to do so may result in malfunction due to noise.
[Installation Precautions]
• Shut off the external power supply for the system in all phases before mounting or removing the
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
[Installation Precautions]
• Use the programmable controller in an environment that meets the general specifications
described in "Safety Guidelines", the manual supplied with the CPU module or head module.
Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of
the product.
• To interconnect modules, engage the respective connectors and securely lock the module joint
lever. Incorrect interconnection may cause malfunction, failure, and drop.
• Do not directly touch any conductive parts and electronic components of the module. Doing so
can cause malfunction or failure of the module.
