Page 9: C1120 Configuration
The field "S5-CommChannnel" describes the base address for the parallel channel functions (see chapter "parallel channel" ). For use of more than one C1120 cards in one PLC the base address default of 250 for the communication channel can be changed to an other address ( from address 128 - 250, length 6 Byte ). - Page 10 For use of more than one C1120, the word alignement can be disabled by overwriting a "0". The default setup value of "0" in the field "Error request" enables the C1120 to stop the PLC with a timeout status of the C1120 in case errors occur on the II/O-Lightbus System, the C1120 interface deletes the I/O addresses in the Dual Ported RAM mapped to the PLC in case of error.
- Page 11 The pageswitch mechanism displayes the newest process image memory page to the PLC. Entering a “ 1” in the field PLC IRQ Frame causes the C1120 to send an extra control and interrupt message frame for triggering a local process image cycle on the intelligent peripheral modules.

Page 13: C1120 I/O Memory Map List
Ident number. Warning ! The interface card C1120 is not able to identify modules. If the I/O list and physical order of modules are different, or the inputs and outputs are set up incorrectly by DIP switches, I/O data is transferred erroneous from the PLC program to the modules without recognition. - Page 14 C1120 S5 to II/O-Lightbus Interface Beckhoff II/O-Lightbus System Function keys HELP displays help text. INSERT MODULE by pressing "F2" a new module is inserted at the current cursor position. The address is set to the equivalent line number. Following module addresses are incremented.
- Page 15 Example given: the modules 1 and 2 are mapped as direct modules. The STEP5 program accesses the I/O addresses 23 to 26, the C1120 maps the I/O data to the modules 1 and 2: IB 23, IB 24 from module 1...
- Page 16 PLC (PB/PY 254): Bit 1 acts as life bit and changes status every cycle. By reading the life bit the programmer can recognize and count cycles (refer also to chapter "status register S5/C1120). Example: In above shown setup screen the modules 3 and 4 are mapped indirect. The base address for indirect communications list is set up to 60, number of indirect modules is 2.
- Page 17 II/O Lightbus communication with the C1120 interface. The C1120 interface card responds with setting the bit 0 of PB/PY 254 (ACK bit): the data byte contents are valid and can be read by the PLC with L PB. The PLC handshakes with resetting the bit 0 of PB/PY 254 (strobe bit).

Page 26: Status Register S5 / C1120
Beckhoff II/O-Lightbus System Status register S5 / C1120 The C1120 interface occupies the addresses PB/PY 250 to PB/PY 255 by default. This setup is configurable. By generating a single transfer to peripherial byte PB/PY 255 (T PB 255) the C1120 interface is interrupted for a single request. The peripherial byte PB/PY 254 is the status register C1120. -
