Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

Address space for configuration as 1 x 32-channel DI 16x24VDC/DQ 16x24VDC/0.5A BA
The figure below shows the address space assignment for configuration as a 1 x 32-channel
module (16 digital inputs / 16 digital outputs). You can freely assign the start address for the
module. The addresses of the channels are based on the start address.
The letters "a" to "d" are printed on the module. "EB a", for example, stands for module start
address input byte a.

Address space for configuration as 4 x 8-channel DI 16x24VDC/DQ 16x24VDC/0.5A BA S
For the configuration as a 4 x 8-channel module, the channels of the module are divided into
multiple submodules. The submodules can be assigned to different IO controllers when the
module is used in a Shared Device.
The number of usable submodules depends on the interface module used. Please observe
the information in the manual for the particular interface module.
Unlike the 1 x 32-channel module configuration, each of the four submodules has a freely
assignable start address.

Address space for configuration as 1 x 32-channel DI 16x24VDC/DQ 16x24VDC/0.5A BA MSI/MSO
For configuration as a 1 x 32-channel module (module-internal Shared Input, MSI/Shared
Output, MSO), the channels for inputs or outputs 0 to 15 of the module are copied to multiple
submodules. Each of the channels 0 to 15 are then available with identical values in various
submodules. These submodules can be assigned to up to four IO controllers when the
module is used in a Shared Device:
●The IO controller to which submodule 1 is assigned has write access to output channels 0
to 15 and read access to the input channels 0 to 15.
●The IO controllers to which submodule 2, 3 or 4 is assigned have read access to the input
channels or output channels 0 to 15.
The number of usable submodules depends on the interface module used. Please observe
the information in the manual for the particular interface module.
Value status (Quality Information, QI) for inputs
The meaning of the value status depends on the submodule involved.
For the 1st submodule (=basic submodule), the value status is not relevant.
For the 2nd to 4th submodule (=MSI submodule), the value status 0 indicates that the value
is incorrect or the basic submodule has not yet been configured (not ready for operation).
Value status (Quality Information, QI) for outputs
The meaning of the value status depends on the submodule involved.
For the 1st submodule (=basic submodule), the value status 1 indicates that the output value
specified by the user program is actually output at the module terminal.
Possible causes for value status = 0:
●Value is incorrect, for example, because the supply voltage is missing.
●IO controller of the basic submodule is in STOP mode.
For the 2nd to 4th submodule (=MSO submodule), the value status 1 indicates that the
output value specified by the user program is actually output at the module terminal.
Possible causes for value status = 0:
●Value is incorrect, for example, because the supply voltage is missing.
●IO controller of the basic submodule is in STOP mode.
●The basic submodule is not yet configured.
