Compatibility/compatibility mode
• The 2nd generation current / voltage measuring modules also function with older
SIMOCODE basic units. In this case, they behave compatibly with the 1st generation
current / voltage measuring modules and can replace them in an application
(compatibility mode). The prerequisite is that the current setting must lie within the
permitted range of the 2nd generation current/voltage measuring module. Example: A
1st generation current / voltage measuring module 3UF7111-1AA00-0 (2.4 - 25 A) is to
be replaced. If the current setting lies within the range of 2.4 to 3.0 A, a 2nd generation
current / voltage measuring module 3UF7110-1AA01-0 (0.3 - 4 A) must be used.
• If both the SIMOCODE pro basic unit and also the current / voltage measuring module
are replaced and the hardware parameterization is unchanged (the SIMOCODE ES
parameterization still contains a 1st generation current / voltage measuring module), the
compatibility mode of the current / voltage measuring module is also active.
• In the event that a 1st generation current / voltage measuring module is replaced by a
2nd
generation current / voltage measuring module, an existing decoupling module must
be removed to ensure fault-free operation.
Specifically, this means:
• The tripping characteristic remains as in the 1st generation current / voltage measuring
modules.
• The measurement accuracy figures and measured values correspond to those of the 1st
generation current / voltage measuring modules.
• The new measured values stored as float in the data records are not entered
(see manual SIMOCODE pro - Communication
(https://support.industry.siemens.com/cs/ww/en/view/109743960
)
→ Tables, data records - definitions").
The following restrictions still have to be observed:
Maximum configuration of the SIMOCODE system with older basic units
SIMOCODE pro V PB (≤ E14) or pro V MR (E01) and a 2nd generation current / voltage
measuring module
• When using BU / UM+: max. 4 expansion modules
• When using BU / UM+ / OP:
– max. 4 expansion modules
– max. 3 expansion modules when using AM, TM and EM
• when using BU / UM+ / OPD: Max. 3 expansion modules, of which one AM, TM or EM
or max. 2 expansion modules from AM, TM and EM when using a BU 24 V DC
• when using BU / UM+ / OPD: Max. 2 expansion modules, of which one AM, TM or EM
when using a BU 110-240 V AC/DC
In this case, the installation guidelines for configuration with the 2nd generation current /
voltage measuring modules must be observed.
