Description
■Before instruction execution
Specify the number of resends to be performed if the instruction is not completed
within the monitoring time specified by (s1)+8.
• 0 to 15 (times)
■At completion of instruction
The number of resends performed (result) is stored.
• 0 to 15 (times)
[CC-Link IE Controller Network or CC-Link IE Field Network]
Specify the monitoring time until completion of processing. If processing is not
completed within the monitoring time, the request is resent by the number of
resends specified in (s1)+7.
■When "0" is specified in bit 8 of (s1)+0
• 0: 10s
• 1 to 32767: 1 to 32767s
■When "1" is specified in bit 8 of (s1)+0
• 0: 10s
• 1 to 65535: 1 to 65535100ms
[Ethernet]
Specify the monitoring time until completion of processing. If processing is not
completed within the monitoring time, the request is resent by the number of
resends specified in (s1)+7.
■When "0" is specified in bit 8 of (s1)+0
Specify the TCP resend timer value or greater for the monitoring time till completion
of processing.
• 0 to (TCP resend timer value): The TCP resend timer value is assumed as the
monitoring time.
• (TCP resend timer value + 1) to 16383: (TCP resend timer value + 1) to 16383s
■When "1" is specified in bit 8 of (s1)+0
• 0: 10s
• 1 to 65535: 1 to 65535100ms
Specify the number of words to be read.
■When reading data from RCPU, QCPU, or LCPU
• Channels 1 to 8 are used: 1 to 960 (words)
• Channels 9 and 10 are used: 1 to 8192 (words)
■When reading data from QnACPU
• 1 to 480 (words)

The validity status (valid or invalid) of the data in (s1)+12 and later is stored. Note
that the data in (s1)+12 and later is not cleared even when the instruction is
completed successfully.
• 0: Invalid
• 1: Valid
Upper 8 bits: Month (01H to 12H)
Lower 8bits: Year (00H to 99H: Upper two digits of the year)
Upper 8 bits: Hour (00H to 23H)
Lower 8 bits: Day (01H to 31H)
Upper 8 bits: Second (00H to 59H)
Lower 8 bits: Minute (00H to 59H)
Upper 8 bits: Year (00H to 99H: Upper two digits of the year)
Lower 8 bits: Day of the week (00H (Sun.) to 06H (Sat.))
■When "0" is specified in bit 15 of (s1)+0
The network number of the station in which an error was detected is stored. (No
information is stored if an error is detected in the own station.)
• 1 to 239 (Network number)
■When "1" is specified in bit 15 of (s1)+0 (Ethernet only)
The IP address (third and fourth octets) of the station where an error was detected is
stored.
