Stores the number of total slave stations that are actually connected by data link in CC-Link IE
Field Network.
Range: 1 to 120 (0 when own station is disconnected)
Stores the maximum station No. of the stations where the baton pass is performed.
Range: 1 to 120 (0 when own station is disconnected)
(Condition)
• This is enabled when Baton pass status (own station) (SB0047) is off.
Stores the maximum station No. of the station where the cyclic transmission is performed.
Range: 1 to 120 (0 when own station is disconnected)
(Condition)
• This is enabled when Data link status (own station) (SB0049) is off.
Stores the connection status of own station.
08H: Normal (communication in progress on PORT1, no PORT2)
18H: Disconnecting (cable disconnected on PORT1, no PORT2)
28H: Disconnecting (establishing line on PORT1, no PORT2)
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 (cumulative) count that was detected for cable disconnections at the PORT1.
When Clear communication error count (SB0006) is turned on, the stored occurrence rate is
cleared.
When FFFFH is counted, the value returns to 0 and the module continues to count.
Stores the (cumulative) count that error data was received at the PORT1.
The count stores only error data that is not transmitted to all stations.
When Clear communication error count (SB0006) is turned on, the stored occurrence rate is
cleared.
When FFFFH is counted, counting stops.
Stores the (cumulative) count that data was received at the PORT1.
When Clear communication error count (SB0006) is turned on, the stored occurrence rate is
cleared.
When FFFFFFFFH is counted, counting stops.
Stores the count of the network event history.
This stored count is cleared when Event count clear (SB0009) is turned on.
When FFFFH is counted, the value returns to 0 and the module continues to count.
