1. Overview
Describe the specifications of WPMZ series original command communication.
This manual is intended for engineers who connect WPMZ series to the the master device and create control
/ data collection processing.
As a master device, it is assumed to be a PC or Programmable Logic Controller (PLC). Please prepare the
equipment to be used for the master in advance.
First of all, please refer to "2. Communication condition " and set so that the module (WPMZ - 1/3) connected
to the master device conforms to the communication specifications.
If the communication protocol is original, refer to "4. Originalcommand" of the corresponding module
according to "3. Original command communication specification" and control and read necessary items.
Or, if the communication protocol is unique and continuous output, refer to "6. Unique continuous output
response" of the corresponding module according to "5. Originaloutput communication specification" and
read the necessary items.
For the Modbus RTU protocol, another manual is available so please inquire.
1-1. What can be done with this function?
For products with RS-232C option output, you can select Modbus protocol and original protocol. The
following table shows the contents that can be communicated by each protocol.
Note that only Modbus protocol can be selected for products with RS-485 option output, and original
protocols can not be selected.

3. Originalcommand communication specification
Describe the behavior when protocol setting is set to "originalcommand".
The originalcommand is a single master / single slave method.
A message is sent from one master to the slave (WPMZ).
3-1. Communication procedure (Protocol setting“Originalcommand”)
When the protocol setting is set to "Originalprotocol", the following operation is performed.
Master sends a command message, the slave (WPMZ) sends a response message to the contents
of the message.
The operations of the master side message and the slave side message are as follows.
3-2. Communication procedure（Protocol setting“Originaloutput”）
The following operation is performed under the condition that the protocol setting is set to "Original
output".
The slave (WPMZ) periodically sends messages to the master and does not receive messages from
the master. The operations of the master side message and the slave side message are as follows.
