design and implement, DeviceNet has the capability to interconnect complex as well as
simple devices to the same network, easily accommodating both analog and discrete I/O.
Westlock Controls is a member of ODVA and our DeviceNet products are conformance
tested and certified.
1.4 Westlock Intellis DeviceNet Module EL-40092
The EL-40092 module is a 4 input, two output network monitor. Inputs 0 and 1 are
internal Hall Effect sensors that are activated by the field of a magnet (south pole). Inputs
2 and 3 are active high/low (activated by pulling the input up to +24V or activated by
pulling the input down to ground). The outputs are open drain active low FETs, fused
(solid state self resetting) at 0.2A with diode protection to 24Vdc. For current
consumption see Table 6, page 1-8. Minimum power supply input voltage is 19Vdc to
insure proper solenoid operation.
Connection to the network is via DeviceNet specific cable. There are both Round and
Flat Media Refer to the Allen-Bradley document “DeviceNet Cable System”’ (Cat. No.
DN-6.72) for a detailed treatment of this topic.
For data exchange to occur each network monitor connected to the DeviceNet network
must be programmed with a unique address, numbered between 0 and 63 and all nodes
must be set to the same Baud rate as the scanner. This may be accomplished via setting
the DIP switch, S1, on the electronics module.
The address and Baud rate may also be set via explicit Messaging if positions 7 and 8 on
S1 are set to the “On” position. Refer to Section 3.1, page 3-2 for additional information.
It is possible to exchange or add slaves during normal operation without interfering with
communications to other nodes.
The Westlock Controls Corp. DeviceNet Module, EL-40092, operates as a GROUP 2
Only Slave on a DeviceNet network. The unit supports Explicit Messages and Polled I/O
Messages of the Predefined Master/ Slave Connection Set. The device does not support
the Explicit Unconnected Message Manager (UCMM).
Refer to Section 1.5 Device Specifications, page 1-7, for a summary of features.
