7. Linking the data devices
• From LE-40MTB-E to the programmable controller
By monitoring the data in the D500 to D599 in the programmable controller, the data shown in the
table below can be monitored.

Ten points of 16 bits, D490 to D499, can be transferred from the programmable controller to the
LE-40MTB-E. It means that when the number of data to be sent to the LE-40MTB-E becomes 11
or more, data transfer is impossible. To solve this problem, a set value No. is assigned to a data
device having an even number, and the contents of the data is assigned to a data device having
an odd number. Then, up to five data can be sent at a time. And all the data in the table can be
sent by sending it on the time sharing basis.
Data is transferred in the following way.
[1] The data is set to the D490 Å` D499.
[2] The M807 is turned on at the programmable controller.
[3] The LE - 40MTB-E receives the data.
[4] When receiving is completed, the M907 is turned on.
[5] The programmable controller receives the M907.
[6] The M807 is turned off at the programmable controller.
[7] The LE-40MTB-E receives "OFF" of the M807.
[8] The M907 is turned off.
[9] "OFF" of the M907 is received.
[10] Data transfer is completed. The next data will be transferred.
When four or less data is sent, set "0" to the data to be sent to all the remaining buffer memories
having an even number. When data devices will not be transferred, set "0" to the data in the D490
to D499.
While the operation/stop [MC1] is turned on, the system setting data is neglected even if it is trans-
ferred. Make sure to transfer the data while the [MC1] is turned off.
The decimal point is neglected in any data.
The time required to transfer five data is as follows.
Required time (ms) = 100 + (Operation cycle in the master programmable controller)
