Configuring Modules for Communication on a Remote I/O Network 35

4. Configure the 1756-DHRIO module parameters.

1756-DHRIO Module Properties Dialog Box

In This Field: Do the Following:

Name Type a name for the module (i.e.,DHRIO_module_in_slot_1).

Slot Type or select the slot number where the module is installed.

Type

Channel A

Channel B

Select RIO for the Channel that is connected to the remote I/O network. If only one channel is configured as

a remote I/O scanner, we recommend that you use Channel B. If you configure Channel A as a remote I/O

scanner, you cannot use the programming terminal din connector on the front of the 1756-DHRIO module.

Baud Rate Specify a baud rate for the Remote I/O channel. This value defines the communication rate at which the

1756-DHRIO module scans the remote I/O modules.

Revision Select the major and minor revision level for your module.

Electronic Keying Specify a keying option.

When you configure a module, you specify the slot number for the module. However, it is possible to place a

different module in that slot, either on purpose or accidently. Electronic keying lets you protect your system

against accidental placement of the wrong module in a slot. The keying option you choose determines how

closely a module in a slot must match the configuration for that slot.

Open Module Properties Ensure that this box is checked to access all of the available configuration screens for the module. If this box

is not checked, clicking OK assigns the default parameters for the remaining configuration fields.
