[Design Precautions]
!

WARNING
• When a communication error occurs in the PROFIBUS-DP, the status of the faulty station is
as follows. Configure an interlock circuit in the sequence program using the communication
status information (input X1, buffer memory 2040 (7F8
H ) to 2079 (81F
H
)) so that the system
can operate safely.
Erroneous outputs and mis-operation could cause accidents.
(1) The input data of the master station maintains the data before abnormality of the
communication.
(2) When the master station is down, the output state of each slave station will be in
accordance with the parameter settings.
(3) When any slave station is down, the output state of other slave stations will be in
accordance with the parameter settings of the master station.
• Do not output the "prohibited to use" signal as the output signal to an intelligent function
module from the programmable controller CPU.
Doing so may cause malfunction of the programmable controller system.
