SPC200-COM-IBS 0503a

Designated use

The field bus module type SPC200-COM-IBS has been
designed for connecting the SPC200 to the INTERBUS.
With this field bus module the SPC200 can be operated
as a slave on the remote bus.

The basic components and modules for the SPC200
are described in the User Manual type P.BE-SPC200-...
You must observe at all costs the safety precautions
described therein as well as the designated use of the
individual components and modules. Please observe
also the notes on safety in the operating instructions for
the pneumatic components used. The SPC200 as well
as the modules and cables to be connected may only
be used as follows:

– as intended
– in their original state

– without any modifications

SPC200-COM-IBS 0503a

– in perfect technical condition

If used with additional commercially-available compo­nents, such as sensors and actuators, the specified
limits for pressures, temperatures, electrical specifica­tions, torques, etc. must be observed. Local and na­tional technical regulations must also be observed.

1.4 Operating modes

Whether for control via an I/O module or via a field bus,
the SPC200 offers the following operating modes for
processing the stored NC programs:

•

start/stop mode

•

record select mode

The desired operating mode can be set with the control
panel or with WinPISA. Detailed information on the
operating modes can be found in the user manual for
the SPC200.

The SPC200 communicates with the INTERBUS mas­ter via the internal I/O address ranges (internal
input/output addresses) of the field bus module. De­pending on the operating mode used, field bus module
type SPC200-COM-IBS provides the following I/O bits
for communication with the INTERBUS master:

WARNING
Before starting the fitting work, switch off the follow­ing in the sequence specified here:

1. the compressed air supply

2. the load voltage and operating voltage
supplies on the SPC200 and, if applicable,
on the axis interface string.

You thereby avoid:
– undesired movements of the connected actuators

– uncontrolled movements of loose tubing
– undefined switching states

2. Fitting

2.1 Fitting and removing the field bus module

CAUTION
Incorrect handling can damage the modules.
Do not, therefore, touch the contacts on the modules.
Please observe the regulations for handling electro­statically vulnerable components.

Before fitting or removing modules, discharge yourself
electrostatically, in order to protect the modules from
discharges of static electricity.

The slots are numbered 1 to 6 from left to right. Slot 1
is reserved for the power supply module (type SPC­200-PWR-AIF). The field bus module can be fitted as
desired in slots 2 to 6. If the field bus module is fitted
next to the diagnostic module, a control panel cannot
be plugged in because of the field bus cable.

2-4

Individual identification of all the modules fitted is car­ried out automatically.

Only 1 field bus module may

be fitted.

The modules are fixed onto the rack with the aid of a
safety catch. A tool is not therefore required for fitting or
removing the modules.

SPC200-COM-IBS 0503a

2. Fitting

WARNING
Actuators can be activated unintentionally and the
SPC200 can be damaged if modules are added or
removed while the power supply is switched on.
Before undertaking installation and/or maintenance
work, switch off the following in the sequence
specified here:

1. the compressed air supply

2. the load voltage and the operating voltage
supplies for the SPC200 and, if applicable, the
load voltage supply for the axis interface string.

Fitting

modules

When fitting the modules into the rack, proceed as
follows:

1. Switch off the compressed air supply and the oper­ating voltage supply.

2. If applicable, remove the blind plate.

3. Hold the module by the front plate and push it into
the guide rail. Make sure that the modules are not
tilted when they are pushed in and that no compo­nents on the printed circuit board are damaged.

4. Make sure that the plugs of the terminal strips are
correctly aligned. Using light pressure, push the mo­dule in completely. The safety catches will then lock
automatically (see Fig. 2/1).
