Chapter 4 Configuring the I/O

Figure 18 - MicroLogix 1100/1400 Message Configuration Screens for the Logic

Command, Reference, and Datalink In

General Tab Box Setting

This Controller (data for MicroLogix 1100)

Channel 1 (integral). Controller port to which the network is connected.

Communication Command 500CPU Write. The controller type and command type for the controller to read or write data.

Because the MicroLogix 1100 is part of the SLC-500 controller family, the ‘500CPU’ controller

type was selected. The ‘Write’ command type was selected to write data to the drive.

Data Table Address

(1)

N20:20. An unused controller data table address containing the data to be written to the drive.

Size in Elements

(2)

19. Number of elements (words) to be transferred. Each element size is a 16-bit integer.

Target Device (data for adapter/drive)

Message Timeout 5. Message timeout duration in seconds.

Data Table Address

(3)

N41:0. Specific starting address of the destination file in the drive.

Routing Information File RI9:2. An unused routing information file for the controller.

MultiHop Tab Box Setting

To Address 10.91.100.79. The IP address of the adapter connected to the drive.

(1) For details on data table addresses for this example project, see Table 11…Table 14 starting on page 98.

(2) For details to determine element size for a specific drive, see Understanding Controller Data Table Addresses

on page 97.

(3) For N-File details, see N-Files

on page 192.

TIP

This message will error out if the Control Timeout value is not changed from a non-

zero value. Refer to page 71

for writing a value to the Control Timeout.

TIP

If the controller is controlling more than one drive, it is recommended to

intersperse the control I/O messaging for each drive to conserve network

bandwidth and decrease response time. That is, sequence the message

instructions for each drive so that its group of messages will occur at a different

time than those for another drive.
