4.4 Communications Modules
— 4-133 —
Note When using two MEMOBUS Modules, do not use the same Module number. If you use the
same Module number, the following will result:
• If the two MEMOBUS Modules are mounted to the same Rack, the MEMOBUS Module
mounted to the slot with the larger slot number will not operate normally.
• If the two MEMOBUS Module are mounted to different Racks, the MEMOBUS Module
mounted to the Rack with the larger Rack number will not operate normally.
e) The default communications mode and parameters are as follows:
(1) Communications mode: RTU mode
(2) Communications parameters:
Baud rate: 9,600 bps
Parity check: Yes
Parity:
Even
Stop bits: 1
Data bit length:8
Delay time:
0 ms
f) When the communications mode and parameters of MEMOBUS port is set to the user
settings, you can set and use any settings from the communications modes and pa-
rameters shown in Table 4.54 on page 4-129. Selection is done from the MEMOSOFT.
g) Examples of setting DIP switch are shown below:
Example 1
When the DIP switch is set as shown in the diagram at the right, the ME-
MOBUS Module (RS-232) is set as follows:
• Communications parameters of port 2 are set to the defaults.
• Communications parameters of port 1 are set to the defaults.
• Port 2 is in MEMOBUS Mode.
• Port 1 is in MEMOBUS Mode.
• Port 2 is slave port.
• Port 1 is slave port.
• Module number: 1
• Normal operation mode
