Base units Part names and settings
8 – 10
NOTES Please note, that the maximum number of extension base units, which can be connected to
the main base unit is depending on the CPU type:
Q00JCPU, Q00UJCPU: 2
Q00CPU, Q00UCPU, Q01CPU, Q01UCPU, Q02UCPU: 4
Q02CPU, Q02HCPU, Q06HCPU, Q12HCPU, Q25HCPU: 7
Q02PHCPU, Q06PHCPU, Q12PHCPU, Q25PHCPU: 7
Q03UD(E)CPU, Q04UD(E)HCPU, Q06UD(E)HCPU, Q10UD(E)HCPU,
Q13UD(E)HCPU, Q20UD(E)HCPU, Q26UD(E)HCPU: 7
Q12PRH and Q25PRH: 7 (refer to following note)
The extension base unit cannot be connected when the serial number (first five digits) of the
redundant CPU Q12PRH- or Q25PRHCPU is "09011" or earlier.
For a main base unit with redundant Q12PRHCPU or Q25PRHCPU from serial number
09012… on, the extension is possible with up to seven base units and maximum 63 mod-
ules.
Connect the Q65WRB to the first extension base. Since the Q65WRB is fixed to the first
extension base, base number setting is not required. Use the Q68RB for the second exten-
sion base to the seventh extension base. Set the extension stage number as described
above.
If a prohibited extension stage number is set, "BASE LAY ERROR" (error code: 2010)
occurs.
E
CAUTION:
● Never set more than one jumper on the connector pins of the extension base unit.
● Set the extension stage number for extension base units in the order of connecting,
starting from the one connected to the main base unit. The same jumper setting for
more than one extension base unit or a missing jumper causes malfunction.
