6. Linking the Contact Devices
• When the occupied station number of the FX2N-32CCL is set to three, the contact device can be linked
with 80 points (work) + 16 points(system) for each input and output. However, the number of the con-
tact devices which LE-40MTB-E can handle is eight each for input and output as shown in the table
below.
• To access this device from the master programmable controller, read and write the buffer memory in
the master unit by FROM/TO commands. The remote input (RX) reads and writes the numbers which
correspond to the remote station numbers of the buffer memories #224(EOH) to #351 (15FH). The
remote output reads and writes the numbers which correspond to the remote station numbers of buffer
memories #352 (160H) to #479(1DFH).
• For example, if the host number of the FX2N-32CCL connected to the LE-40MTB-E is set to 1, RX0 to
RX7 gain access to the buffer memory #224(EOH) and RY0 to RY7 gain access to the buffer memory
#352(160H).

7. Linking the Data Devices
• To access the data device from the master programmable controller, read and write the buffer memory
in the master unit by FROM/TO commands in a similar way to the contact device.
• The remote register for write (RWw) to the remote is arranged in the buffer memories #480(1EOH) to
#735(2DFH), and the remote register for read (Rwr) from the remote is arranged in the buffer memories
#736(2EOH) to #991(3DFH).
• Transmission data from the LE-40MTB-E is written periodically (400ms/once) in the remote registers
#0 to #9 of the FX2N-32CCL.
By reading out the remote register assigned to set the host number of the remote station from the master
unit, the LE-40MTB-E's status can be monitored. For example, when the host number of the FX2N-
32CCL is set to 1, the data from the LE-40MTB-E is transmitted to the buffer memories #736(2EOH)
to #745(2E9H) in the master unit.
• The data is sent to the LE-40MTB-E by writing data in the remote register #0 to #9 of the FX2N-32CCL.
Because the LE-40MTB-E can process up to five data ( up to ten devices) at a time, the data should
be written in combination with two operations by the two contact devices, such as the numeric data
transmission completion flag and receipt completion flag. Though up to five data can be sent at a time,
all the data in the table can be sent by sending it on the time sharing basis.
