(3) Number of the error IDs (Un\G8192)
Among the IDs of the connected modules, the number of error IDs that send no response due to disconnection of
the transmission cables (DP, DN) or a failure in the slave module alone is stored. (Up to 128 IDs)
The stored values are retained until the power is turned off and on or Error flag clear command (Yn0) is turned off
and on after the error is solved.
(a) Data update timing
After the automatic address detection, the data are updated as soon as a response error is detected.
(4) Error ID information storage areas (Un\G8193 to Un\G8320)
When the transmission cables (DP, DN) are disconnected or an error occurs in the slave module or an error (error
code: 00CA , 0130 ), the error IDs are stored for the number of error IDs in the ascending order. (Up to 128 IDs)
H H
The IDs to be stored are as follows.
• 0000 to 00FF : ID of output slave modules
H H
• 0200 to 02FF : ID of an input slave module or I/O combined slave module
H H
The stored values are retained until the power is turned off and on or Error flag clear command (Yn0) is turned off
and on after the error is solved.
(a) Data update timing
After the automatic address detection, the data are updated as soon as a response error is detected.
(5) Number of the connected modules (Un\G8960)
The number of slave modules detected by the automatic address detection is stored. (Up to 128 modules)
(6) Number of the IDs of the connected modules (Un\G9216)
The number of the IDs of the connected modules is stored by the automatic address detection. (Up to 128 IDs)
The number of IDs stored is retained even after power-off.
(a) Data update timing
The data are updated at the time of power-on or automatic address detection.
(7) Connected module ID information storage areas (Un\G9217 to Un\G9344)
The ID information of all the slave modules connected to the master module is stored in the ascending order.
The IDs to be stored are as follows.
• 0000 to 00FF : ID of output slave modules
H H
• 0200 to 02FF : ID of an input slave module or I/O combined slave module
H H
The information of IDs stored is retained even after power-off.
(a) Data update timing
The data are updated at the time of power-on or automatic address detection.
