7.2.1
Error displays/remedying errors (incompatibilities)
Below are listed possible fault indicators, and potential remedial measures, when operating
the CP 343−2 with incompatible slaves.
Error
CER indicator flickers or lights up, and
other LEDs may also flicker or light up
(AUP, SF, LEDs 0-9)
Examples of incompatible combinations of AS-i slaves and AS-i master (list not complete):
● Slave of type A/B
● Slave of type A/B (spec. 3.0),
● Slaves of the Combined Transaction Type 2-5 (CTT slaves in accordance
14
Possible cause
A connected slave is not compatible
with the AS-i master since the slave
operates in accordance with a higher
version of the AS-i specification.
For examples, see below.
including A/B slave with 4 inputs/3 outputs (e.g. 3RK2400-1FQ03-0AA3, in accordance
with AS-i spec. V2.1)
on
master 6GK7342-2AH00-0XA0 (in accordance with AS-i spec. V2.0), especially if the
highest output bit of the slave is set in the PLC (output D3 = "1").
including A/B slave with 4 inputs/4 outputs (e.g. 3RK2400-1DQ00-0AA3, in accordance
with AS-i spec. V3.0)
or A/B slave with 4 outputs (e.g. 3RK2100-1CT30-0AA3, in accordance with AS-i spec.
V3.0)
or A/B slave with analog profile 7.A.9 (e.g. 3RK2207-1BQ50-0AA3, in accordance with
AS-i spec. V3.0)
on
master 6GK7343-2AH00-0XA0 (AS-i spec. V2.1) or
master 6GK7343-2AH10-0XA0 (AS-i spec. V2.1)
with AS-i spec. 3.0),
including A/B slave with profile 7.A.5 (e.g. 3RK1325-... SIRIUS motor starter M200D AS-i
standard with 2 integral AS-i slaves)
on
master 6GK7343-2AH00-0XA0 (AS-i spec. V2.1) or
master 6GK7343-2AH10-0XA0 (AS-i spec. V2.1)
Remedy
Connect only slaves that are
compatible with the AS-i specification
of the master, or replace the (older)
master with a current AS-i master that
is compatible with the connected
slaves. A master can process slaves if
the version of the slave specification is
equal to or lower than the version of the
master specification.
