20-COMM-E EtherNet/IP Adapter User Manual

The data from the I/O Board is loaded into the Datalink word starting with
bit 0 of Datalink D1 and concluding with bit 14. Bit 15 of Datalink D1 is
reserved as an input valid Status flag. When the input data is valid, bit 15 =
1.

For example, for the 20-XCOMM-IO-OPT1, the digital inputs and digital
outputs are mapped as shown in

Figure 9.4

and

Figure 9.5

respectively.

Important: On power-up or reset, the outputs will be in a ‘non-activated’

state.

Configuring the Adapter to

Use the Optional I/O Data

To configure the adapter to use the optional I/O Board, Parameters 23 -
[DPI I/O Cfg], 35 - [M-S Input], and 36 - [M-S Output] must be set. To
send input/output data from the optional I/O board to the network, do the
following:

• Turn on bit 4 (1xxxx) in Parameter 35 - [M-S Input]

• Turn on bit 4 (1xxxx) in Parameter 36 - [M-S Output]

• Turn off bit 4 (0xxxx) in Parameter 23 - [DPI I/O Cfg]

Setting the Datalink D bit 4 in the M-S Input and M-S Output parameters
directs the communication adapter to send Datalink D back to the controller.
Turning off bit 4 in the DPI I/O Cfg parameter directs the communication
adapter to not send Datalink D data back to the drive. For more information
on I/O Messaging and Configuring Datalinks, see

Chapter 5

Using the I/O

If the I/O Board Fault Action Jumper (JMP1) is set to the Fault
Configurable position, Parameter 33 - [Flt Cfg D1 In] is used to set the
states of the outputs when the I/O Board takes its Fault Action. For details
on setting the Fault Action Jumper, see the I/O Board Option Installation
Instructions, publication 20COMM-IN002.
