Description
Stores the current value of the link scan time during cyclic transmission.
The stored value contains a maximum error of 1 ms. (Unit: ms)
(Conditions)
This is enabled when the Baton pass status (own station) (SB0047) is OFF.
Stores the setting value of the contact link scan that is set in the supplementary
setting.
• 0: No setting
• 1 to 200: Setting value of contact link scan time (Unit: ms)
(Conditions)
This is enabled when the Data link status (own station) (SB0049) is OFF.
Stores the connection status of own station.
• 00H: Normal (communication in progress on PORT1 and PORT2)
• 01H: Normal (communication in progress on PORT1, cable disconnected on
PORT2)
• 04H: Normal (loopback communication in progress on PORT1, cable disconnected
on PORT2)
• 10H: Normal (cable disconnected on PORT1, communication in progress on
PORT2)
• 11H: Disconnecting (cable disconnected on PORT1 and PORT2)
• 12H: Disconnecting (cable disconnected on PORT1, establishing line on PORT2)
• 21H: Disconnecting (establishing line on PORT1, cable disconnected on PORT2)
• 22H: Disconnecting (establishing line on PORT1 and PORT2)
• 40H: Normal (cable disconnected on PORT1, loopback communication in progress
on PORT2)
Stores the link scan time during cyclic transmission. (Unit: μs)
Stores the occurrence rate (maximum value) of received error frames at the own
station's PORT1. (Unit: %)
When Clear communication error count (SB0006) is turned ON, the stored occurrence
rate is cleared.
Stores the occurrence rate (current value) of received error frames at the own station's
PORT1. (Unit: %)
When Clear communication error count (SB0006) is turned ON, the stored occurrence
rate is cleared.
Stores the occurrence rate (maximum value) of received error frames at the own
station's PORT2. (Unit: %)
When Clear communication error count (SB0006) is turned ON, the stored occurrence
rate is cleared.
Stores the occurrence rate (current value) of received error frames at the own station's
PORT2. (Unit: %)
When Clear communication error count (SB0006) is turned ON, the stored occurrence
rate is cleared.
Stores the number of the station where loopback is being performed. The other
loopback station number can be checked by Loopback station number 2 (SW0071).
• 0: No loopback stations
• 1 to 120: Slave station
• 125: Master station
• 255: Station number not set
If a station whose station number duplicates is performing loopback, this register
stores the duplicated number.
(Conditions)
This is enabled when Baton pass status (own station) (SB0047) is OFF and Network
configuration mismatch occurrence status (SB0098) is OFF.
