1. Function Description - Hardware
M2510
General
The module M2510 is an input module used in the II/O system. By ADU four analog input
values in the form
a) 0 to +10V
b) 0 to 1V
c) 0 to 20mA
d) -10 V to +10V
e) -1 V to +1V
can be used. The resolution is 12 bit, so that, in a single telegram of the II/O system parallel
transmission of 2 ADU's is possible.
The whole module uses 2 addresses in the II/O system.
There are four LEDs for system diagnosis. Working normally, only the green LEDs "CYCLE
(XILINX1)" and "CYCLE (XILINX2)" are switched on. In case an error is detected the red
"ERROR (XILINX1)" "ERROR (XILINX2)" LEDs are switched on (according to the type of
failure, one or two of the LEDs).

2. Function Description - Software
The 4 ADCs work in stand alone mode. They are triggered by the 'CYCLE' signal, when the
telegram is received.
When the twelve bit of data are read, the transformation result of the previous cycle is used.
There is no need for selection or other communications, since all control signals needed are
created by the hardware.
As there are always 2 ADCs read in a 32 bit telegram, two addresses in the II/O system have
to be reserved for the whole module.

4. Installation Notes
Mounting
The M2510 is connected to the fibre optic ring using fibre optic connections (Beckhoff
Z1000). The maximum length of the FO cable, leading to the neighbouring boxes, should not
be more then 600m for glass fibre or 45 meters for other fibres. These values are only valid if
for bending the cable a radius of at least 30 mm is used. If plastic fibres are used, no special
tools are needed for installation of the plugs.
The M2510 is installed at the machine or simply by installing it to a cartridge carrier
according to DIN EN 50022 or DIN EN 50035.
Configuration
Before setting the system to work the desired modes of the Analog transformers have to be
adjusted by setting certain jumpers according to the following configuration table:
Input Jx.1 Jx.2 Jx.3 Jx.4 Jx.5 Jx.6

Adjusting and Testing of Analog Inputs
The module M2510 is configured to the measuring range 0 to 10V per default. It can be
delivered with customized configuratin and adjustment.
Every analog input of the M2510 can be adjusted indepenedently of the other inputs if
necessary (e.g. change of the measuring range).
First the appropriate jumpers have to be set. Then an adjustment of the mode concerned can
be done:
a) unipolar 0-10 V
- connect input with ground
- read channel by II/O Lightbus test program or other II/O-Lightbus software
(continuously to provide constant transformation)
- use potentiometer "Offset unipolar" to adjust the value read to "0"
b) unipolar 0-1 V
- connect input with ground
- read channel by II/O Lightbus test program or other II/O-Lightbus software
(continuously to provide constant transformation)
- use potentiometer "Offset unipolar" to adjust the value read to "0"
- connect and adjust precisely 1V to the input
and then adjust by using potentiometer"GAIN" to the value "FFFh
c) unipolar 0-20 mA
- connect input with ground
- read channel by II/O Lightbus test program or other II/O-Lightbus software
(continuously to provide constant transformation)
- use potentiometer "Offset unipolar" to adjust the value read to "0"
- connect and adjust precisely 20mA to the input
(alternatively 1V with 50 Ohm burden, or 10V with 500 Ohm burden)
and then adjust by using potentiometer"GAIN" to the value "FFFh
d) bipolar +/-10 Volt
- connect input with ground
- read channel by II/O Lightbus test program or other II/O-Lightbus software
(continuously to provide constant transformation)
- adjust by using potentiometer "Offset bipolar" the read in value to "800h"

e) bipolar +/-1 Volt
- connect input with ground
- read channel by II/O Lightbus test program or other II/O-Lightbus software
(continuously to provide constant transformation)
- adjust by using potentiometer "Offset bipolar" the read in value to "800h"
- connect and adjust precisely -1V to the input
and then adjust by using potentiometer"GAIN" to the value "000h
Spannungsversorgung
There is a two-pin terminal (X10 Pin1+2) for the supply voltage with connections for control
logic (+).
