Conditions for Selecting and Using the Successor Model
Note
If a defective device needs to be replaced , it is recommended to use a replacement device that has the same item number instead of the successor model.
Exchange when Redesigning, Revising or Modifying a System
When designing a new system or revising an existing machine , it is recommended to use the latest and most powerful devices. The successor models offer all the well-known advantages of the previous Bihl+Wiedemann ASi modules, plus a wealth of new functions and the best value for money.
Comparison of functions and technical features
When designing a new system or modernising an existing machine, it is important to select the right device with the required technical features.
Especially, when exchanging an ASi module or ASi Safety module with a successor model in an existing machine, care must be taken to ensure that particular technical characteristics are as similar as possible or even better (depending on the desired upgrade of the machine) than the one you have:
- Number of (safe) inputs or outputs
- Number of allocated ASi addresses/ASi nodes per ASi circuit
- Supply voltage from ASi or from AUX
- Max. supply current/derating
- Number and position of connections for ASi, AUX and peripheral devices
- Pin assignment for modules with M12/M8 connections
- Dimensions
- Required version of Bihl+Wiedemann software suites for configuration, diagnostics and commissioning
The successor models recommended by Bihl+Wiedemann are always as similar as possible to the respective archive articles with regard to the above criteria and at the same time they offer as many new functions and improved technology as possible.
Number and Position of Connections/Dimensions
The number and position of the connections for peripheral devices (sensors, actuators) as well as for ASi and AUX (auxiliary power) vary to a certain extent between archived items and successor models depending on the design and performance characteristics of the particular device. In some cases, the dimensions between the devices may also differ.
Please make sure that there is sufficient space available for installation in the electrical cabinet and that the connecting cables are of sufficient length.
For the corresponding technical details, please refer to the datasheet and the attached documentation. An Eplan macro is also available for each unit as a download on the respective product detail page.
Bit Assignment
The bit assignment of the I/O data or process data can vary to a certain extent between archived items and successor models (e.g. number of inputs/outputs, use of the parameter bits) depending on their features and function range. Please check in advance whether your desired application requires adjustments in the programming of the higher level control.
For the corresponding technical details please refer to the datasheet and the attached documentation. If you have any questions about the bit assignment of ASi modules, please feel free to contact our support team at any time.
ASIMON360 and ASi Control Tools360 With Hardware Catalog
In order to make optimal use of the ASi modules from Bihl+Wiedemann, it is recommended to use the current version of the ASIMON360 or ASi Control Tools 360 software.
Not all successor models may be included in the hardware catalog of older Bihl+Wiedemann Software Suites (BW2916, BW2902).
It is recommended to check the Bihl+Wiedemann Software Suite regularly for updates via Help > About > Check for Updates.
