6.3 RAS Information Reading Data
This section describes the RAS information of the DN211 (RAS counter, event history, execution
node information) read by the ladder program. See "4.6.6 RAS Information Read Request" for
RAS information reading request.
6.3.1 The RAS Counter
When you specify "1" for request information type at RAS information read request, the RAS
counter can be read on to the acknowledgement area. Individual items in the RAS counter of the
DN211 have one byte data in size.
"H" or "L" in address column in Table 6.4 indicates the high-order byte or the low-order byte of the
register area read.
H: F-8 bits side
L: 7-0 bits side
Acknowledgement area
F 87 0
