USING THIS DOCUMENT
This document is an addendum to the standard DLC bulletin and describes
the use of the DeviceNet^TM connection to the DLCN. This document should be
read in conjunction with the DLC bulletin.
GENERAL DESCRIPTION
The Model DLCN, Dual Loop Controller with DeviceNet, has a similar
feature set and specifications as the standard Dual Loop Controller. The DLCN
operates as a DeviceNet Slave, providing a connection to a standard DeviceNet
network. Once a valid MAC ID and Baud Rate have been established, the
supported attributes (see table: DLCN DeviceNet SUPPORTED ATTRIBUTES)
can be accessed by a Master, providing control and status functions for each
PID loop. The DLCN can also be fully programmed via the built-in RS485
communications port using our Windows^® based RLCPro configuration
software (refer to the DLC bulletin).
In addition, the model DLCN can be used as a simple analog data acquisition
device for monitoring T/C's, RTD's, voltage and current over a DeviceNet
network.

PROGRAMMING THE DLCN via RLCPro
In order to program the DLCN via RLCPro, the DeviceNet bus cable must
be disconnected from the unit. This causes the internal DLCN communication
bus to automatically switch to the front panel Modbus programming port. When
programming is complete, the unit may be attached to the DeviceNet bus, thus
disabling the front panel port and enabling DeviceNet communications. The
DLCN Modbus communication parameters are fixed at 19200 baud, unit
address of 247, 8 data bits, no parity, RTU mode. The DIP and Rotary Switches,
as described below, are used for DeviceNet settings only.
SETTING THE MAC ID and BAUD RATE
The DLCN DeviceNet MAC ID is set using two rotary switches allowing the
ID to be set in standard decimal notation (e.g. MAC ID = 27, SWC = 2, SWB
= 7 ) from 0 to 63. (64-99 are not used.) The baud rate is set with DIP switches.
The following table explains the baud rate settings.
DIP SWITCH SETTING TABLE
SWITCH SWA
1 off, 2 off
1 on, 2 off
1 off, 2 on
1 on, 2 on
SETTING
Force 125 K baud
Force 250 K baud
Force 500 K baud
Autobaud Detect (factory default)
Autobaud will match the DLCN DeviceNet baud rate to the network baud
rate within 5 seconds every time the DLCN power is cycled. The DLCN
must be connected to a bus carrying valid message traffic. In noisy
environments autobaud may not be able to properly detect the network baud
rate. In this case, manually set the baud rate as required.
Note: Configuration of MAC ID and baud rate is not supported over
DeviceNet.
MOD/NET STATUS LED
The MOD/NET Status LED provides a visual indication to the operator of
the current status of the DeviceNet interface. The DLCN primary power and
DeviceNet power must be applied for correct LED function.
What to look for:
A. Startup:
LED flashes Green for 0.25 sec, then Red for 0.25 sec, then Off.
B. LED Off:
This device is the only device on the network (waiting for an
acknowledgment to its duplicate MAC ID check), or this device is not
powered.
C. Flashing Red LED:
An I/O connection has timed out, or a recoverable error has occurred.
D. Flashing Green LED:
The device is functioning correctly and is waiting to be
commissioned by a bus master.
E. Solid Red LED:
The device has encountered a non-recoverable fault, such as a
duplicate MAC ID response, and has removed itself from the bus.
F. Solid Green LED:
The device is on line, functioning correctly and has been
commissioned by a bus master.
