with a high risk level which, if not avoided, will result in death or severe injury.
WARNING!
A safety notice on an orange signal bar with the signal word WARNING designates a haz-
ard with a medium risk level which, if not avoided, might result in death or severe injury.
CAUTION!
A safety notice on a yellow signal bar with the signal word CAUTION designates a hazard
with a low risk level which, if not avoided, could result in minor or moderate injury.
2.2 General instructions
In addition to the safety notices, these instructions contain information that must be observed to

Product description
3 PRODUCT DESCRIPTION
3.1 Components and properties
The product EtherCatWPM Gateway is part of the WPM pressure monitoring system. A compo-
nent specially developed for monitoring and registering
FIBRO WPM pressure sensors located inside or outside of a registered pressing tool.
The product EtherCatWPM Gateway records status information from WPM pressure sensors
and the WPM data holder using the Bluetooth LE 4.0 standard in the FIBRO usage data proto-
col.
Additionally, the WPM pressure sensor, the WPM data holder and the WPM configuration soft-
ware work together with the product EtherCatWPM Gateway.
3.2 Accessories
No additional accessories are planned for the WPM Gateway.
M12 line connectors from various industrial line manufacturers are required for operation.

10/40 Operating instructions EtherCatWPM Gateway Fieldbus
Assembly
4 ASSEMBLY
The WPM Gateway is mounted on the press or in the immediate vicinity of the press or pressing
tool using a holder and at an easily visible, mechanically protected location.
Four M6 screws are used to attach it. The screw must be effectively secured against uninten-
tional loosening.
The WPM Gateway should be mounted so it is aligned horizontally and so the LED displays can
be seen easily.
The radio’s send direction is always indicated symbolically on the upper side (with the label “FI-
BRO”) of the WPM Gateway.
Cabling should go down and to the side. Use an angled M12 plug connector.
A large area around the radio send direction (labelled on the surface) must be kept free.
It should be possible to view the pressing tool without and hindrances.
The distance between the pressing tool (distance from the WPM Gateway to the WPM data
holder and the WPM pressure sensor) should not exceed 5 metres.
4.1 Constructive requirements
Ample space must be kept free around the WPM Gateway with the exception of the side where
it is attached.
The area of the WPM Gateway labelled with a radio symbol must not be near metallic surfaces
and must not come into direct contact with them.
For operation with radio technology, the data holder must be mounted so that the line of sight to
the corresponding WPM Gateway is unimpeded.
There must be a drain for liquids. The area around the WPM Gateway must not be flooded with
operating materials.

Operation
6.2 Configuration operation
The WPM Gateway does not need external configuration.
The EtherCAT communication and data are configured via PLC.
An EtherCAT XML file (device description file) is available for this purpose.
6.3 Normal operating modes
The WPM Gateway has four operating modes:
• Simple digital I/O operation for systems without EtherCAT,
• Pairing with tools
• Fieldbus operation for complete integration into system control
• The option of using WPM configuration software to access the radio interface directly
– This function is currently deactivated
6.3.1 Normal digital I/O operation
For digital IO operation, there are 4 digital inlets, 4 digital outlets and 3 relays available.

WPM pressure sensors are in order
Blinking During active tool monitoring, at least one moni-
tored sensor did not receive any information for
a period exceeding 120 seconds
D1_OUT
Signal light is orange,
status is warning.
On At least one connected WPM pressure sensor or
WPM data holder has a warning
D2_OUT
Signal light is red,

On Connection successfully completed,
tool monitoring is active.
Blinking (1) The gateway creates a connection with the
pressing tool and scans all the WPM compo-
nents connected to it
Blinking (2) If D0_OUT is blinking:
During active tool monitoring, at least one moni-

Operation
6.3.2 Pairing of the WPM data holder and WPM Gateway
In normal operation, a WPM Gateway monitors exactly one configured pressing tool.
This pressing tool must be made known to the WPM Gateway.
If a WPM system is equipped with a WPM Gateway, the login button on the
WPM data holder serves as manual confirmation for the manual pairing.
Inlets for controlling the pairing:
The digital inlet D0_IN switches the WPM Gateway to pairing mode. In this operating mode, the
WPM Gateway waits for the confirmation of a WPM data holder, which is triggered by the button
“Login” being pressed. The digital outlet D3_OUT makes a connected display blink.
