1.2 Coated modules
Coated modules are X20 modules with a protective coating for the electronics component. This coating
protects X20c modules from condensation and corrosive gases.
The modules' electronics are fully compatible with the corresponding X20 modules.
For simplification purposes, only images and module IDs of uncoated modules are used in
this data sheet.
The coating has been certified according to the following standards:
• Condensation: BMW GS 95011-4, 2x 1 cycle
• Corrosive gas: EN 60068-2-60, method 4, exposure 21 days
1.2.1 Starting temperature
The starting temperature describes the minimum permissible ambient temperature in a voltage-free state
at the time the coated module is switched on. This is permitted to be as low as -40°C. During operation, the
conditions as specified in the technical data continue to apply.
Information:
It is important to absolutely ensure that there is no forced cooling by air currents in the
closed control cabinet, e.g. due to the use of a fan or ventilation slots.

1) The power consumed externally for operating the module discharges via the GND contact of the power supply module and must therefore be taken
into account in the power balance of the power supply module.

3.1 Digital inputs
The module is equipped with 12 digital input channels.
3.1.1 Recording the input state
Unfiltered
The input state is collected with a fixed offset to the network cycle and transferred in the same cycle.
Filtered
The filtered state is collected with a fixed offset to the network cycle and transferred in the same cycle.
Filtering takes place asynchronously to the network in multiples of 200 µs with a network-related jitter of
up to 50 µs.
Packed outputs (only function model 0 - Standard)
Setting "Packed inputs" in the Automation Studio I/O configuration can be used to determine whether all
bits of the register should be applied as individual data points in the Automation Studio I/O mapping ("Dig-
italInput01 to DigitalInputxx") or whether the register should be displayed as a single UINT data point ("Dig-
italInput").
Information:
The register is described in "Input state of digital inputs 1 to 12" on page 12.
3.1.2 Input filter
An input filter is available for each input. Disturbance pulses that are shorter than the input delay are sup-
pressed by the input filter.

tDelay ⇒ Input delay
The input delay can be set in steps of 100 μs. It makes sense, however, to enter values in steps of 2 since
the input signals are sampled in an interval of 200 μs.

4.1 Using the module on the bus controller
Function model 254 "Bus controller" is used by default only by non-configurable bus controllers. All other
bus controllers can use other registers and functions depending on the fieldbus used.
For detailed information, see section "Additional information - Using I/O modules on the bus controller" in
the X20 user's manual (version 3.50 or later).
4.1.1 CAN I/O bus controller
The module occupies 2 digital logical slots on CAN I/O.

5.1 General data points
In addition to the registers described in the register description, the module has additional general data
points. These are not module-specific but contain general information such as serial number and hardware
variant.
General data points are described in section "Additional information - General data points" in the X20 Sys-
tem user's manual.

Fixed modules require their data points to be in a specific order in the X2X frame. Cyclic access occurs
according to a predefined offset, not based on the register address.
Acyclic access continues to be based on the register numbers.

5.5 Minimum cycle time
The minimum cycle time specifies how far the bus cycle can be reduced without communication errors
occurring. It is important to note that very fast cycles reduce the idle time available for handling monitoring,
diagnostics and acyclic commands.
Minimum cycle time
Without filtering 100 μs
With filtering 150 μs
5.6 Minimum I/O update time
The minimum I/O update time specifies how far the bus cycle can be reduced so that an I/O update is
performed in each cycle.
Minimum I/O update time
Without filtering 100 μs
