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

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 (that is, 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 accidentally. Electronic keying lets you protect your system
against accidental placement of the wrong module in a slot. The keying option that you choose determines
how closely a module in a slot must match the configuration for that slot.
Open Module Properties
Verify that this box is checked to access all available configuration screens for the module. If this box is not
checked, clicking OK assigns the default parameters for the remaining configuration fields.
