As-I Design; Connection Options; Number Of Connectable Control Heads; Bus Line Length - Burkert 8681 Démarrage Rapide

9 AS-I DESIGN
9.1 Connection options
Connection left:
1 x M16 x 1.5 cable gland with multipole connection (M12 plug
according to IEC 61076-2-101, 4-pole) to an 8 cm or 80 cm
long cable
Connection right:
1 x M16 x 1.5 cable gland for external initiator
9.2 Number of connectable control
heads
In AS interface versions with extended addressing range (A/B slave),
1 master can communicate with 62 slaves.
In AS interface versions with addressing range 31 slaves, a maximum
of 31 control heads can be connected to a bus line (the address range
restriction).
9.3 Bus line length
The bus cable may be a maximum of 100 m long. When designing the
system, consider the length of the round cable leading directly to the
control head (see example calculation in the operating instructions).
