Mitsubishi Electric CR800 Series Ethernet Function Instruction Manual page 20

2 Preparation before use
(5) COMDEV (Definition of devices corresponding to COM1: to 8)
When using the data link function, the setup is necessary.
Definition of device corresponding to COM1: to 8 is set. COM1: to 8 is used for OPEN command of the robot program.
Be sure to set it only when the data link is specified on setting of the protocol (CPRCE11 to 19).
The setting values of the Ethernet function correspond to the port Nos. which are set at the parameter NETPORT.
* In the following parameters NETOPORT (n) and COMDEV(n), n indicates the element No. of that parameter.
The device name set
n
up by COMDEV(n)
1 OPT11
2 OPT12
3 OPT13
4 OPT14
5 OPT15
6 OPT16
7 OPT17
8 OPT18
9 OPT19
For example, if the port No. specified at NETPORT(3) is allocated to the data link of COM:3, the following will be applied.
COMDEV(3) = OPT13
CPRCE13 = 2
(6) NETMODE (server specification)
Set up, when using the data link function.
Set the TCP/IP communication in the data link function of the robot controller as the server or the client.
It is necessary to change with the application of the equipment connected to the robot controller.
(7) NETHSTIP (The IP address of the server of the data communication point)
Set up, when using the robot controller as a client by the data link function.
Specify the IP address of the partner server which the robot controller connects by the data link function.
Set up, when only set the robot controller to the client by server specification of NETMODE.
(8) MXTTOUT (Timeout setting for executing real-time external control command)
This is changed when using real-time external control command and setting the timeout time for communication with the
robot controller.
Set a multiple of the control cycle (refer to the following).
Controller
CR750/CR751 series
CR800 series
When the real-time external control command is executed, the timeout time during which no communication data is
received by the robot controller from the personal computer is counted up. If the count reaches the value set in MXTTOUT,
the operation will stop with the error (#7820). For example, to generate an error when there is no communication for
approx. 7 seconds, set 1000 for the CR750/CR751 series, and 2000 for the CR800 series (1000 when user mechanical is
set).
This setting is set to -1 (timeout disabled) as the default.
(9) NETGW (Gateway address)
Specify the gateway address to communicate with the PC of on other network.
2-6
Port number
The port number specified by NETPORT(2)
The port number specified by NETPORT(3)
The port number specified by NETPORT(4)
The port number specified by NETPORT(5)
The port number specified by NETPORT(6)
The port number specified by NETPORT(7)
The port number specified by NETPORT(8)
The port number specified by NETPORT(9)
The port number specified by NETPORT(10)
* OPT13 is set at 3rd element of COMDEV.
* Set up as a data link.
