Communications
Outline of Communications
With a personal computer or host NC connected with MINAS-E Series through RS232C-compliant serial
communications, you can do the following:
(1) Rewriting parameters
(2) Browsing and clearing status and history of alarm data
(3) Monitoring control status including status, I/O, etc.
(4) Saving and Loading parameters
Advantages
•You can write parameters all at once from the host when starting the machine.
•As you can display operating condition of the machine, serviceability will improve.
Note that the following application programs for a personal computer and cables are available for use. For
information of PANATERM®, refer to the instruction manual of PANATERM®.
For the latest version, please contact us.

Communications Specification
Connection of Communications Line
MINAS-E Series has RS232C communications port. and is capable of communications between the host as follows:
RS232C Communications
In RS232C communications, a host and the driver are connected 1:1 and communicate with each other
according to the RS232C transmission protocol.
You can change settings of the module ID with Pr00. In particular, you may set the same module ID unless
there is management problem on the host side.

Communications Method
Set RS232C communications baud rate with Pr0C. Any change to these parameters will be valid when you
power on the control power supply. For detailed information, refer to list of parameters related to the following

Time for data transmission is calculated with the following expression, for instance, in the case of 9600 [bps]:
When the baud rates of 2400 bps and 4800 [bps] are used, data transmission time will be 4.17 [ms/byte] and
2.08 [ms/byte], respectively. Note, however, actual communication time will be added time necessary for
processing received command, and necessary for switching between a line and transmission/reception control.

Handshaking Code
For line control, the following codes are used.
ENQ …When the module has a block to transmit, it sends ENQ.
EOT …When the module is ready to receive a block, it sends EOT. The line enters transmission mode when
sending ENQ and receiving EOT. It enters reception mode when receiving ENQ and sending EOT.
ACK …When a received block is judged normal, ACK is returned.
NAK …When a received block is judged as abnormal, NAK is returned. A judgment is made based on
checksum and timeout.

Line Control
Direction of transmission and conflict are solved.
Reception mode …The module enters reception mode after receiving ENQ and returning EOT.
Transmission mode …The module enters transmission mode after sending ENQ and receiving EOT.
When there occurs a conflict between the transmitting module and receiving module:
When subsequent to transmission of ENQ, a slave receives ENQ while waiting for EOT, priority is given to
ENQ sent from a maser, and the slave enters the reception mode.
Transmission Control
Entering transmission mode, a module transmits a command block continuously and then waits for reception
of ACK. When the module receives ACK, transmission is complete. When the number of transferred
command bytes is incorrect, ACK may not be returned. When ACK is not returned within T2 period, or when
NAK or any code other than ACK is received, transmission retry will be executed. The retry will start with
ENQ.
Receiving Control
Entering receiving mode, the module receives transmitted blocks continuously. It obtains the number of
command bytes from the first byte, and receives as many command bytes as that number plus 3. When the
sum of received data is zero, reception is considered successfully ended and ACK is returned. When
abnormal checksum or timeout between characters occurs, NAK is sent.

Configuration of Data Block
A data block to be transmitted in physical phase is configured as illustrated below:
N : This is the number of command bytes (0 - 240),
which indicates the number of parameters needed by a command.
axis : This defines a module ID assigned to parameter No.00 axis name of the driver. (1 - 15)
command : This is the control command (0 - 15).
mode : This is the command execution mode (0 - 15),
which differs depending on a command.
check sum : This is 2’s complement of the total number of bytes, ranging from the first byte to the byte immedi-
ately before the checksum byte.

Protocol Parameter
The following parameters can control transfer of a block. A user can set these parameters to any value with INIT
command to be described later.
T1 .... •This is allowable time between module identification byte and ENQ/EOT, or time from reception of a
character code by this device to that of a next character code in a transmission/reception data block.
When this specified time is exceeded, timeout error occurs and NAK is returned to the transmitting
module.
T2 .... •This is allowable time after this device transmits ENQ till it receives EOT. When this specified time is
exceeded, it means that the receiving module is not ready to receive data or fails to receive ENQ code
for some reason. In this case, ENQ code will be resent to the receiving module (number of retries).
•This is allowable time after EOT is sent out till a first character is received. When this specified time is
exceeded, NAK is returned and the receiving mode ends.
•This is allowable time after checksum byte is sent out till ACK is received. When this specified time is
exceeded, ENQ code is resent to the receiving module, as in the case of reception of NAK.
RTY .....This shows the maximum number of retries. When this specified value is exceeded, transmission error
occurs.
M/S ..... This shows switching of a master/slave. When conflict of ENQ transmission occurs, this parameter
determines to which priority is given. (0=slave mode, 1=master mode) Transmission of the module
defined as a master should take precedence.

Example of Data Communication
Example of Changing Parameters
The following illustrates time-series communications data flow when a change is made to a parameter.
Communications should be conducted in the sequence of outline, (1) individual writing of parameters and (2) writing
to EEPROM if storage is needed. In this example of hardware connection, the device is directly connected with a
host through RS232C communications with user ID=1. Data is represented in hexadecimals.
(Note) For details of commands, refer to “List of Communications Commands”on Page 166.

This command just changes a parameter temporarily. If you wish to write to EEPROM, execute writing to EEPROM of
parameter (mode=4)
Be sure to set 0 to unused parameters. Otherwise, data error will occur.

Transmitted data
This command is used to write a set parameters to EEPROM.
Transmission data will be returned after completion of EEPROM writing.
Writing to EEPROM may take approx. 5 seconds max. (if all parameters are changed).
When writing of parameters fails, data error will occur.
When control power supply LV is detected, control LV of error code will be returned, and parameter writing will be disabled.
