General Tab Box
Setting
This Controller (data for MicroLogix 1100 controller)
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 controller 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

TIP: This message will error out if the Control Timeout value is not
changed from a non-zero value. Refer to
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.
