The Controller backplane is part of the Controller chassis. The front side contains the connectors for the Control Processor modules. The keying pins in the backplane connect the module housings with ground. The below figure shows the front view of an empty redundant Controller chassis, showing the Controller backplane.

The back side of the Controller backplane contains all the connectors for signals that go in or out of the (non-)redundant Controller. These connectors are visible when the back cover plate is swung upwards (see Figure 3).

The Controller backplane connects the 5VR output of the PSU of CP1 with the 5VR output of the PSU of CP2.

The resulting 5V-R is used to supply the non-redundant IO.

Thanks to the output diodes in the PSU-240516 (see Figure 2) the 5V-R will be available as long as (at least) one of the PSUs is operating.

The figure on the next page shows the 5V connection of the two PSU-240516 modules on the Controller backplane.

Connector function

The table on the next page describes the function of the connectors on the back side of the Controller backplane.

IO Chassis for non-redundant IO modules (Safety Manager)

The IOCHAS-0001S is a chassis for up to 18 non-redundant IO modules. It consists of the following components:

The above figure shows the front side of an empty IOCHAS-0001S with the front-cover raised. A 19″ chassis has 21 slots for modules (each 4TE wide). These slots are numbered 1 to 21, starting at the lefthand side of the chassis.

In the IOCHAS-0001S, slots 1 to 18 are available for IO modules.

IO Housing

The IO housing is specifically designed for Safety Manager.

It is a 19″ based housing.

A coverplate assembly at the front of the chassis shields the flatcables of the IO modules. This cover can be swung upwards to access the flatcables. To swing the cover upwards, unlock it by moving the two locking slides horizontally towards the middle of the chassis. The backside of the IO cover assembly provides room for a tagnumber assignment drawing.

The backside of the IO housing is covered by an IO back cover plate that can be removed by rotating the half-turn locking screw anti-clockwise (see the below figure).

IO cable clamp support (with tie wrap) at the back of the IO housing leads all cables towards the side of the IO chassis.

Figure 6-10 shows a front view of a filled IOCHAS-0001S with the cover opened.

Figure 6-11 shows a front view of a filled IOCHAS-0001S with the cover closed.

The below table lists the connectors present on the IOBUS-HBS.

The above figure shows the front side of an empty IOCHAS-0001R with the front cover raised.

A 19″ chassis has 21 slots for modules (each 4TE wide). These slots are numbered 1 to 21, starting at the left-hand side of the chassis. In the IOCHAS-0001R, slots 1 to 18 are available for IO modules. They are configured in pairs

The IO modules in the odd numbered slots (and the IO-0001 in slot 20) are controlled by Control Processor 1.

The IO modules in the even numbered slots (and the IO-0001 in slot 21) are controlled by Control Processor 2

Slot 19 cannot be used.

Slot 20 and slot 21 contain the IO-0001 modules.

IO Housing

The IO housing is specifically designed for Safety Manager.

It is a 19″ based housing.

A cover plate assembly at the front of the chassis shields the flatcables of the IO modules. This cover can be swung upwards to access the flatcables. To swing the cover upwards, unlock it by moving the two locking slides horizontally towards the middle of the chassis. The backside of the IO cover assembly provides room for a tag number assignment drawing.

The backside of the IO housing is covered by an IO back cover plate that can be removed by rotating the half-turn locking screw anti-clockwise (see the below figure).

The pin allocation of each respective input and output module can be found in the module datasheet. The figure on the next page shows the pin mapping from an IO chassis connector at the front to both a SIC cable (CNx) connector and a converter (Px) connector at the back of the IO Chassis.

The below table lists the connectors on the IOBUS-HBR.

CPCHAS-0002

Chassis for redundant Controller (Safety Manager A.R.T.)

The Controller chassis CPCHAS-0002 is used to contain the Control Processor modules. Each Safety Manager has one Controller chassis. The Controller chassis is generally located at the top position in the cabinet, and the IO chassis at lower positions.

A Controller chassis contains the following components:

Controller housing

Controller backplane

Controller housing

The Controller housing has been designed specifically for Safety Manager. It is a 19″ housing that is open at the front and covered at the back.

Control Processor modules are placed in the chassis through the front of the housing with the use of module guides, which are located at the bottom and top plate of the housing.

The modules are locked in the chassis with the quarter turn fasteners, located below the module-grips.

The below figure shows the front of a filled redundant Controller chassis.

The back of the housing is covered by a magnetically locked back cover plate, which can be swung upwards to reveal the Controller backplane.

Cables must be tie-wrapped to one of the three horizontal bars at the back of the housing, to lead them towards the side of the chassis.

The top bar is reserved for the 24V-supply and 24V-signal wires/cables.

The middle bar is reserved for the communication cables.

The bottom bar is reserved for the 5V and Watchdog cables (WdPx and 5V-x).

The figure 6 – 21 shows the back of an empty Controller chassis.

Location of Control Processor modules

The Controller chassis CPCHAS-0002 contains all Control Processor modules.

The below table shows the location of the Control Processor modules in a redundant Controller (as seen from the front of the cabinet). As you can see, all Control Processor modules are doubled in a redundant Controller configuration, with the exception of the Battery and Key switch module, which is shared by both Control Processors.

For each Quad Processor Pack, room is provided for two communication modules in the Controller chassis. The below table shows possible locations for different combinations of communication modules.

Controller backplane

The Controller backplane is part of the Controller chassis. The front side contains the connectors for the Control Processor modules. The keying pins in the backplane connect the module housings with ground.

The below figure shows the front view of an empty redundant Controller chassis, showing the Controller backplane.

The back side of the Controller backplane contains all the connectors for signals that go in or out of the Controller. These connectors are visible when the back cover plate is swung upwards (see “Back view of an empty Controller chassis” on page 111).

Connector function

The below table describes the function of the connectors on the back side of the Controller backplane.

IOCHAS-0002S

The IOCHAS-0002S is a chassis for up to 18 non-redundant IO modules. A 19″ chassis has 21 slots for modules (each 4TE wide). These slots are numbered 1 to 21, starting at the left-hand side of the chassis.

In the IOCHAS-0002S, slots 1 to 18 are available for IO modules.

Behind the blind front at slot 19, board is located.

Slot 20 and slot 21 contain the IO-0002 modules.

IO Housing

The IO housing is specifically designed for Safety Manager.

It is a 19″ based housing.

A coverplate assembly at the front of the chassis shields the flatcables of the IO modules. This cover can be swung upwards to access the flatcables. To swing the cover upwards, unlock it by moving the two locking slides horizontally towards the middle of the chassis. The backside of the IO cover assembly provides room for a tagnumber assignment drawing.

The backside of the IO housing is covered by an IO back cover plate that can be removed by rotating the half-turn locking screw anti-clockwise (see the below figure).

Attention: The IO back cover plate will be completely unattached from the IO chassis after the locking screw has been turned. Be careful not to drop it.

IO cable clamp support (with tie wrap) at the back of the IO housing leads all cables towards the side of the IO chassis.
