I/O displays
The status of the additional digital inputs on the I/O module SK CU4-IOE is indicated by the relevant LEDs.

3.4.3.4 Termination resistor
Termination of the system bus is carried out at both of its physical ends by switching in the relevant
termination resistors (DIP switches). If the IO module forms such an end, the relevant DIP switch "S-Bus
term." must be set to "ON".
3.4.3.5 Addressing
Up to eight I/O modules can be used on a system bus. By assignment of a specific address and designation
of the "first" or "second" or "second" module, up to two I/O modules can be assigned to each frequency
inverter. Alternatively, there is also the possibility of making one or two I/O modules available to up to four
frequency inverters in parallel (→ Broadcast mode).
It must be noted:

Addresses: Setting exclusively via DIP switch (No.: 02 and 03) in binary code
(„S-Bus Addr. Bit 0“ and „S-Bus Addr. Bit 1“)

Definition of 1st or 2nd I/O module: Setting exclusively via DIP switch (No.: 12)
("2nd IOE Mode")

Changes of address: only become effective after switching the I/O module off and on again

With the use of two I/O modules for each frequency inverter it does not matter whether
these are two SK CU4-IOE modules, two SK TU4-IOE modules or one of each modules.

Up to hardware version V1.1 R1 and firmware version V1.0 R1 of the I/O - extension and
firmware version V1.1 R2 of the frequency inverter only the evaluation of one
I/O - expansion per frequency inverter is possible.

Up to firmware version V1.0 R1 of the I/O extension and firmware version V1.1 R2 of the
frequency inverter, only one I/O extension is possible for each frequency inverter.
NOTE
Care must be taken that each address is only assigned once. In a CAN-based network
(See also Section 9.7), the double assignment of addresses may lead to misinterpretation
of the data and therefore undefined activities in the system.
