Description
Stores the maximum value of the link scan time during cyclic transmission. (Unit:
ms)
(Conditions)
• This register is enabled when 'Baton pass status of own station' (SB0047) is off.
• When 'Baton pass status of own station' (SB0047) is turned on (error), data prior
to error is held.
Stores the minimum value of the link scan time during cyclic transmission. (Unit: ms)
(Conditions)
• This register is enabled when 'Baton pass status of own station' (SB0047) is off.
• When 'Baton pass status of own station' (SB0047) is turned on (error), data prior
to error is held.
Stores the present value of the link scan time during cyclic transmission. (Unit: ms)
The stored value contains a maximum error of 1ms.
(Conditions)
• This register is enabled when 'Baton pass status of own station' (SB0047) is off.
• When 'Baton pass status of own station' (SB0047) is turned on (error), data prior
to error is held.
Stores the setting value of the constant link scan time that is set in "Supplementary
Cyclic Settings" of "Application Settings".
0: No setting
1 to 200: Setting value of constant link scan time (Unit: ms)
(Conditions)
• This register is enabled when 'Data link error status of own station' (SB0049) is
off.
Stores the connection status of the own station.
00H: Normal (communication in progress on P1 and P2)
01H: Normal (communication in progress on P1, cable disconnected on P2)
04H: Normal (loopback communication in progress on P1, cable disconnected on
P2)
10H: Normal (cable disconnected on P1, communication in progress on P2)
11H: Disconnecting (cable disconnected on P1 and P2)
12H: Disconnecting (cable disconnected on P1, establishing line on P2)
21H: Disconnecting (establishing line on P1, cable disconnected on P2)
22H: Disconnecting (establishing line on P1 and P2)
40H: Normal (cable disconnected on P1, loopback communication in progress on
P2)
Stores the link scan time during cyclic transmission. (Unit: s)
Stores the occurrence rate (maximum value) of received error frames at the P1 side
of the own station. (Unit: %)
When 'Clear communication error count' (SB0006) is turned on, the stored value for
the occurrence rate is cleared.
Stores the occurrence rate (present value) of received error frames at the P1 side of
the own station. (Unit: %)
When 'Clear communication error count' (SB0006) is turned on, the stored value for
the occurrence rate is cleared.
Stores the occurrence rate (maximum value) of received error frames at the P2 side
of the own station. (Unit: %)
When 'Clear communication error count' (SB0006) is turned on, the stored value for
the occurrence rate is cleared.
Stores the occurrence rate (present value) of received error frames at the P2 side of
the own station. (Unit: %)
When 'Clear communication error count' (SB0006) is turned on, the stored value for
the occurrence rate is cleared.
