Each number in the table represents a station number.
• When the CPU unit equipped with the MELSECNET/H network module with external
power supply function is turned off, the data link error detection timing may be delayed.
To detect the data link error immediately in this case, create a program by configuring
an interlock with the link relay (LB) in each station's send range.
(Conditions)
• This register is enabled when 'Baton pass error status of own station' (SB0047) is off.
When 'Baton pass error status of own station' (SB0047) is turned on (error), data prior
to error is held.
• Stations exceeding the maximum station number are ignored.
Stores the parameter communication status of each station.
Off: Parameter communication completed or not executed
On: Parameter communication in progress
