Communication tab in Configuration option
Insert Press Insert button to determine the connecting device name and
the controller:
It is used to set the connecting controller. Available connecting
controller will be different depending on HMI type the user uses.
(DOP AE and AS series HMI can support three max. different
controllers simultaneously.)
Delete It is used to delete the existed connecting controller (One project
needs to connect at least one controller).
Insert / Delete
Controller
Connection
Update Modify the connecting controller or change the controller name.
COM Port It is used to set the COM port used to communicate with HMI
(COM1 or COM2). COM3 port is only provided in some types of
HMI, e.g. DOP AE and AS series.
Password Entering a password is necessary for some connecting controllers
before communication.
Comm. Delay
Time
It is used to set a delay time for the startup of an external
controller (i.e. PLC). The range is within 0 ~ 255 ms.
Timeout It is used to set communication time out time when communicating
with the external controller. The range is within 100 ~ 65535ms.
Retry Count HMI will try to send communication command to the external
controller repeatedly if the external controller does not respond
during communication. This option is used to set the number of
retry count times. A communication error dialog box will not
appear unless the number of retry count times is reached. The
range is within 0 ~ 255 times.
Optimize Use this option to enable optimization function. If optimization
function is enabled, all read addresses of all related elements will
be optimized.
Size Limit This function is available only when “Static” in “Optimize Type”
option on Standard tab is selected. It is used to avoid the screen
updating speed from slowing down when reading a long
continuous address.
When the check box next to “Communication Interrupt times then cancel connected”
is checked, HMI will stop communicating with the external controllers after the
communication interrupt times are reached. The purpose of this function is to avoid a
communication error dialog box will show on the HMI screen when a communication
error occurs after HMI has retried. The range is within 1 ~ 255 times. If the user
wants to recover the communication between HMI and controller again when HMI
stop communicating with the external controllers after the communication interrupt
times are reached, the user can use Bit 0 of the control block D1 (suppose that the
stating address is D0) to control HMI communication. When Bit 1 is set to ON, it will
disable HMI communication. When Bit 1 is set to OFF, it will enable HMI
communication. Please refer to Chapter 5 for more description.
HMI Station It is used to set HMI station number. The range is within 0 ~ 255.
Controller Settings
PLC Station It is used to set PLC station number. If PLC does not set station
number, it will use this default setting. The range is within 0 ~ 255.
