2.1.1 Access through absolute addresses
Theaccessto system blocks throughabsoluteaddressesis madeinaccordancewith theIEC1131-3
standard.
• For inputs: %IXa.b.c
• For outputs: %QXa.b.c
( a = module number, b = word address and c = bit adress)
Example: system block DIGITAL_IO (DIGIN):

2.1.2 Module numbers
The system blocksof theautomationsystem 9300 Servo PLC carry the following module numbers:
Module number System block
1 DIGITAL_IO
11 ANALOG1_IO
12 ANALOG2_IO
21 DF_IN_DigitalFrequency
22 DF_OUT_DigitalFrequency
31 CAN1_IO
32 CAN2_IO
33 CAN3_IO
41 AIF1_IO_AutomationInterface
42 AIF2_IO_AutomationInterface
43 AIF3_IO_AutomationInterface
51 STATEBUS_IO
101 CAN_Management
102 CAN_Synchronization
121 DCTRL_DriveControl
131 MCTRL_MotorControl
141 FCODE_FreeCodes
151 SYSTEM_FLAGS
161 AIF_IO_Management
The module number is a part of the absolute address of an SB.
• Example of an input address: %IXa.b.c
( a = module number, b = word address and c = bit adress)
