Figure 14 - MicroLogix 1100/1400 Message Configuration Screens for the Control

Timeout

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 the control timeout value to the drive.

Data Table Address

(1)

N20:0. An unused controller data table address containing the control timeout value to be written.

Size in Elements

(2)

1. 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)

N42:3. Specific starting address of the destination file in the drive.

Routing Information File RI9:0. 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 details on setting the control timeout value and its function, see N-Files

on page 192. The Control Timeout (N42:3) is stored in RAM. If the 20-

COMM-ER adapter is power cycled, the Control Timeout Message must be re-sent. If the Control Timeout is not changed from a non-zero value, the

control message (page 75

) will error out.

TIP

The Control Timeout (N42:3) must be changed to a non-zero value (5…20 seconds

recommended). If the Control Timeout is not changed from a non-zero value, the

control message (page 75

) will error out. The Control Timeout is stored in RAM. If

the adapter is power cycled, the Control Timeout Message must be re-sent.
