[Design Precautions]
• Do not write data into the "system area" of the buffer memory in the intelligent function module.
Doing so may cause malfunction of the programmable controller system.
• Depending on the failure of the external output transistor, there may be cases where the output
is on or off status. Configure an external monitoring circuit for output signals that may lead to
major accidents.
• Do not install the control lines or pulse input lines together with the main circuit lines or power
cables.
Keep a distance of 150 mm (5.9 inch) or more between them.
