Startup with double slave GLK31A
Startup
Assigning the
slave address
An AS-Interface master according to the AS-Interface specification 3.0, rev. 2 in
conjunction with the M4 master profile is required for controlling the GLK31A double
slave.
DRC drive units with GLK31A AS-Interface option are delivered with address 0 and
profile S-7.A.7.7. If you set an address > 0, the GLK31A option turns into a double slave
with profiles S-7.A.7.7 (A slave) and S-7.A.F.5 (B slave). After the address assignment,
the B slave automatically assumes the base address of the A slave.
You have the following options for assigning the AS-Interface address of the DRC drive
unit with AS-Interface option GLK31A (address 1 - 31):
• Addresses are assigned automatically
1)
within a configured AS-Interface system
when replacing a DRC drive unit with AS-Interface option GLK31A.
The following requirements must be met:
– The new DRC drive unit with AS-Interface option GLK31A must have the address
0.
– If you replace several DRC drive units with AS-Interface option GLK31A, you
must replace them individually (one after the other).
• Manual address assignment via the plant master.
The drives must be connected to the AS-Interface cable one after the other. Doing
so prevents several DRC drive units with AS-Interface option GLK31A from having
assigned the same address.
• Manual address assignment using a hand-held AS-Interface programming device.
Observe the notes in the next chapter when connecting the DRC drive unit with AS-
Interface option GLK31A to the AS-Interface cable.
1) AS-Interface master must support this function.
INFORMATION
Observe the following notes if you change the AS-Interface address of the GLK31A
AS-Interface option after it has already been assigned an address (address > 0):
• The new address must not be used by another projected slave.
• The B slave must always have the same base address as the A slave.
• Only the address of the A slave must be set for the address assignment.
• After having assigned the address, the B slave automatically assumes the base
address of the A slave.
