2.1.5.4 Configuration Rules for I/O Modules
With use of external I/O Modules please pay attention to the following rules.
General
• The total power of all modules must not exceed the available power of the power supply
module
• The total power of the external I/O Modules must not exceed the following values:
─ CP-8000: 5 W
─ CP-802x: 7 W (PS-862x), 8 W (PS-864x)
(when using the fiberoptical interface CM-0847, 1 W is less available)
• I/O Modules with a power consumption >800 mW must be mounted as of the first slot
• Maximal 2 AO modules possible, with 2-line arrangement only in the first line permitted
• Mixing of current and voltage on the same AI module is not possible
• Mixing of binary information and pulse commands on the same DO module is not possible,
except with usage of the categories DO_SX and DO_DX (for details refer to manual
SICAM RTUs Common Functions Peripheral Elements According to IEC 60870-5-
101/104, chapter "Binary Information and Command Output"
Mixing of signals on one module DO-820x or DO-821x:
─ Mixing of DO_SX, DO_DX, DO_SC_1.5POL and DO_DC_1.5POL possible
─ Mixing of DO_SC_1POL and DO_DC_1POL possible
─ Mixing of DO_SC_2POL and DO_DC_2POL possible
─ Mixing of DO_SX and/or DO_DX with DO_SC_1POL and/or DO_DC_1POL not possi-
ble
• With use of AI-8510 (with current measurement), for each module a CM-8820 must be
equipped; the modules CM-8820 must be always equipped at the end of a module line or
at a separate line
Option “Assignment of Return Information to Pulse Command”
• With the parameter-settable assignment the sequence of DI modules and DO modules is
arbitrary
• With the fixed assignment respectively after a DI-811x (DI-610x) a DO-821x (DO-62xx)
must be equipped
For further details refer to section 9.1.11.5.5, Command Output.
Option “Checked Command Output” (applies for CP-8000 with SICAM TM I/O Modules)
• Only 1 command output basic module may be connected, alternatively
─ DO-6220, command output according to IC1
─ DO-6221, command output according to RC1
• The command output via DO-6220 or DO-6221 without a DO-6230 is not possible
• Up to 7 command output relay modules DO-6230 may be connected
• The command output via DO-6230 without a DO-6220 or DO-6221 is not possible
• On a DO-6230 either 1-, or 1.5- or 2-pole impulse commands can be assigned (mixture on
the same module is not permitted)
• Additionally, further DO module types can be used
For further details refer to section 9.1.11.5.5, Command Output.
