Logical installation on the X-Bus
The Atrium processor logically occupies the same slot as a TSX P57/TSX H57 processor (rack with address 0, position 00 or 01).
The TSX RKY EX rack with address 0 must have a power supply module and the position which is normally taken up by a TSX P57/TSX H57 processor will be unoccupied (virtual slot for the Atrium processor).
As Premium PLCs have two types of power supply (standard and double format), the unoccupied position on the rack with address 0 will be depend upon the type of power supply used.
NOTE:
-
The slot corresponding to the Atrium processor address (physically free on the rack) must not be used by another module.
-
The X-Bus address must be configured using the micro-switches on the processor card, so that the Atrium processor is aware of its address on the X-Bus.
Using a standard format power supply module
In this case, the installation rule for the rack with address 0 is as follows:
-
the power supply module automatically occupies position PS,
-
position 00, the virtual slot for the processor, must be unoccupied,
-
the other modules are installed starting at position 01.
The following diagram shows the module installation rule when a single format power supply module is used.
Using a double format power supply module
In this case, the installation rule for the rack with address 0 is as follows:
-
the power supply module automatically occupies positions PS and 00,
-
position 01, the virtual slot for the processor, must be unoccupied,
-
the other modules are installed starting from position 02.
The following diagram shows the module installation rule when a single format power supply module is used.
