Maximum Bus Cycle
When 1 through 19 slaves are connected: 3 msec
When 20 through 62 slaves are connected: 0.156 × (1 + N) msec
where N is the number of active slaves
5 msec maximum when 31 standard or A/B slaves are connected
10 msec maximum when 62 A/B slaves are connected
Maximum Slaves
Standard slaves: 31
A/B slaves: 62
When using a mix of standard slaves and A/B slaves together, the standard slaves can
only use addresses 1(A) through 31(A). Also, when a standard slave takes a cer tain
address, the B address of the same number cannot be used for A/B slaves.
Maximum I/O Points
Standard slaves: 248 total (124 inputs + 124 outputs)
A/B slaves: 434 total (248 inputs + 186 outputs)
Maximum Cable Length
AS-Inter face Cable
2-wire Flat Cable When using no repeater or extender: 100m
When using a total of 2 repeaters or extenders: 300m
Single Wires 200 mm
Rated Bus Voltage 30V DC
