16-2 Notes before PLC use
1. The MS300 provides 2 communications serial ports that can be used to download PLC
programs (see figure below).
2. Channel 1 communications format is the same as channel 2.
3. Channel 2 has a preset communications format of 7, N, 2, 9600, ASCII can be changed in
Pr. 09-01 (transmission speed) and Pr. 09-04 (communication protocol).
4. The PLC preset is node 2; the PLC node can be changed in Pr. 09-35, but this address may not
be the same as the drive's address setting of Pr. 09-00.

5. The client can simultaneously access data from the drive and internal PLC, which is performed
through identification of the node. For instance, if the drive node is 1 and the internal PLC node
is 2, then the client command will be
01 (node) 03 (read) 0400 (address) 0001 (1 data item), indicating that it must read the data
in drive Pr. 04-00
02 (node) 03 (read) 0400 (address) 0001 (1 data item), indicating that it must read the data
in internal PLC X0
6. The PLC program will be disabled when uploading/downloading programs.
7. Please note when using WPR commands to write in parameters, values may be modified up to
a maximum of 10
6
times, otherwise a memory write error will occur. The calculation of
modifications is based on whether the entered value has been changed. If the entered value is
left unchanged, the modifications will not increase afterwards. But if the entered value is
different from before, the number of modifications will increase by one.
