Online or Offline Configuration

Devices can be configured before or after installation on a properly-terminated serial bus. If a new device is to be added to an existing bus running at a baud rate other than 153.6 Kbaud standard, the device must first be configured offline. Be careful adding new devices to existing systems. Be sure the baud rate configured for the new device matches that of the system - never mix baud rates on a bus.

Online Configuration

When configuring a device on an operating bus, the Hand-held Monitor must be the ONLY HHM plugged into a device on the bus. If devices are configured online, the HHM automatically check for PLC reference address conflicts.

Offline Configuration

It may be most convenient to configure devices off-line at a central location. Each device will need to be connected to an appropriate source of power and to earth ground. To prepare a device for off-line configuration:

1.Connect a 75 ohm resistor across the Serial 1 and Serial 2 terminals, or use the 75 ohm terminator plug (IC660BLM508).

2.Attach a grounding strap to the device's ground screw. Be sure that the strap is connected to earth ground.

Warnings

If the device is not properly grounded, hazardous voltages may exist. Death or injury may result.

DO NOT TOUCH the connectors or wiring after powering up the device. Hazardous voltages exist, and death or injury may result.

Starting Configuration

Note: To assign a serial bus address, the Hand-held Monitor must be directly attached to the device being configured. Additional features can be configured with the Hand-held Monitor connected at any point on the bus. In that case, the device being configured must be selected as the active device (on the Block/Bus Status screen).

1.Begin with the Hand-held Monitor turned off. Attach the HHM to the device (see below) or to another bus connection point.

2.Turn the Hand-held Monitor on. After the HHM completes its powerup sequence, the Home menu appears. The Hand-held Monitor's Change Block Configuration option must be enabled to complete the instructions in this section. For a new device, the HHM's Change Block ID and Change Block Baud options must also be enabled.
