A
Parameter accessing flag (with handshake)
Parameter accessing flag (with handshake) (RX(n+1)B) turns on when the parameter access processing of Parameter access
request command for the slave module (RY(n+1)0) starts.
■
Turning off Parameter accessing flag (with handshake)
Parameter accessing flag (with handshake) (RX(n+1)B) turns off when both of the following conditions are met.
• The parameter access processing has been completed.
• Parameter access request command for the slave module (RY(n+1)0) has turned off.
Error status flag
The value for Error status flag (RX(n+1)A, RX(n+3)A, RX(n+5)A, RX(n+7)A, RX(n+D)A) is determined by the number of
occupied stations of CC-Link that corresponds to the CC-Link operation mode. (
Error status flag (RX(n+1)A, RX(n+3)A, RX(n+5)A, RX(n+7)A, RX(n+D)A) turns on in the following situations.
• DP/DN short error
• Transmission cable voltage drop error
• DP/DN disconnection error
• Bridge module hardware error
■
Turning off Error status flag
To turn off Error status flag (RX(n+1)A, RX(n+3)A, RX(n+5)A, RX(n+7)A, RX(n+D)A), after eliminating the error, perform either
of the following operations.
Until then, this signal and Slave module alarm signal (RX(n+1)0) remains on.
• Powering off and on the bridge module
• Turning on and off Error reset request flag (RY(n+1)A, RY(n+3)A, RY(n+5)A, RY(n+7)A, RY(n+D)A)
(1) Turn on any of the signals at any timing to start the parameter access.
(2) The signal turns off simultaneously with starting the parameter access processing.
(3) The signal turns on simultaneously with starting the parameter access processing.
(4) The parameter access is in progress.
(5) The signal turns on simultaneously with completing the parameter access processing.
(6) Turn off the signal at any timing.
(7) The signal turns off when the remote output signal is turned off in (6) after the parameter access processing is completed.
