The clock data upon abnormal end is stored in BCD.
This data is stored only when the bit 7 of Abnormal complete type ((S1) + 0)
is 1. The stored value is not cleared even when the dedicated instruction is
normally completed.

Stores the network number of the station that detected an abnormality.
This data is stored only when the bit 7 of Abnormal complete type ((S1) + 0)
is 1. The stored value is not cleared even when the dedicated instruction is
normally completed.
1 to 239 (Network No.)
Stores the station number of the station that detected an abnormality.
This data is stored only when the bit 7 of Abnormal complete type ((S1) + 0)
is 1. The stored value is not cleared even when the dedicated instruction is
normally completed.
1 to 120 (Station number)
POINT
(1) The data read storage device (D1) requires a contiguous free area equal to or
greater than the length of the data read ((S) + 9) (maximum of 960 words).
(2) The number of resends ((S1) + 7) must be set at every instruction execution.
1 The "Set by" column indicates the following:
• User: Data is set by the user before executing a dedicated instruction.
• System: The programmable controller CPU stores the execution result of a
dedicated instruction.
2 For a list of error codes, see the User's Manual (Basic).
3 It can be specified when the local station has an Ethernet module of function
version D or later. (Not available in any other case. Access to the control CPU is
required.)
4 Nothing is stored if the execution source detects an error when receiving an
instruction.
5 When the READ instruction is executed to the redundant system with a control
system or standby system CPU specified, the instruction may be unsuccessfully
completed due to system switching occurred on the target station (error code:
4244 , 4248 ).
H H
If this has occurred, execute the READ instruction again.
6 When data of more than 480 words is specified, a C084
station.
Check the read data length (1 to 480 words) and execute the READ instruction.
7 For how to determine the setting values of the number of resends and arrival
monitoring time and their setting examples, refer to Appendix 1.
REMARKS
The allowable read data length ((S1)+9) of the READ instruction varies depending
on the version. (See the User's Manual (Basic))
Specifying a length value outside the setting range will cause a 4101 error
(OPERATION ERROR) on the local station.
