Expandability
With its expansion bus, the ATL900 can be expanded with the additional modules of the EXP…. series.
Up to three EXP… modules can be installed at the same time.
The EXP… modules supported by the ATL900 are divided into the following categories:
o
communication modules
o
digital I/O modules
o
analog I/O modules
To add an expansion module:
o
remove power from the ATL900.
o
remove one or more protective covers from the expansion slots.
o
insert the upper hook of the module in the specific slot to the left of the expansion slot.
o
turn the module rightwards inserting the bus connector.
o
press until the specific clip on the lower side of the module couples by snapping.
Unless otherwise indicated, the insertion order of the modules is free.
Fit the specific module lock accessory included in the package to improve expansion module fixing safety in applications subjected to strong vibrations.
To fit this accessory:
o
remove the two right screws with a Torx T7 screwdriver
o
position the jumper over the previously coupled modules
o
fasten the screws back in their original seat.
The ATL900 automatically recognises the EXP connected to it when it is powered.
If the system configuration is different from the one last detected (a module was added or removed), the basic unit will ask the user to confirm the new configuration.
If confirmed, the new configuration will be saved and become effective. Otherwise, the discrepancy will be indicated each time the equipment is powered up
The current configuration of the system is shown on the specific display page (expansion modules), indicating the number, type and state of the connected modules.
The I/O numbering is listed under each module.
The I/O and communication channel state (on/off) is shown in negative print.
Additional resources
The expansion modules provide additional resources which can be exploited by means of the respective setting menus.
The setting menus of the expansion units are available also if the modules are not physically present.
Since several modules of the same can be added (e.g. two communication interfaces), there are multiple setting menus all identified by a sequential number.
The following table shows how many modules of each type can be fitted at the same time and in which slots they can be inserted. The total number of modules must be <= 3.
