Output Value Setting For Fieldbus Error - Mitsubishi Electric NZ2FTGN User Manual

Output value setting for fieldbus error

Set the output value of the I/O module for each case, such as when the CPU module status of the master station changes or
a fieldbus error occurs.
The output value changes depending on the following five settings.
 The master station CPU module device to be set at the RY refresh target of the NZ2FT-BT
 The following parameters of the master module
• RJ61BT11 "Output Mode upon CPU STOP": A "Send Remote Output (RY)", B "Send 0 data"
• QJ61BT11N "Case of CPU STOP Setting": A "Refresh", B "Clear compulsorily"
• FX5-CCL-MS "Output Mode upon CPU STOP": A "Send the output data", B "Send 0 data"
 NZ2FT-BT parameter "Output behaviour on fieldbus error"
 Parameter "Substitute value" for each I/O module
 The following parameters of the master module
• RJ61BT11 "Output Mode upon CPU Error"
• QJ61BT11N "PLC Down Select"
• FX5-CCL-MS "Output Mode upon CPU Error"
The data sent from the NZ2FT-C24 to the external device is not affected by the setting of  NZ2FT-GN parameter "Output
behaviour on fieldbus error".
For details on  and , refer to the following.
