Dear All,
Happy new year.In our plant, we are having S7400 PLC. In case of any force of output coil in the logic, it will result in accident. Is there any provision to prohibit the forcing of Outputs? Please help me.
Thank you
You can prevent forcing by changing protect level to level 2 or level 3 in the hardware configuration of the CPU. Forcing will be prevented by a password.
To make the changes modify the CPU properties > protection in the hardware configuration editor.
