2.4 HMI to MP3 Controller Cable
Connect the HMI to the controller DB9 connector using HDR’s null modem cable
#9900666.
See Figure 2 in Section 2.7 for the power/ground wiring connections to terminals 19,
20, and 21 of the controller.
2.5 Communication Configuration
The Proface AST-3201’s RS-232 connects to the DB-9 connector on the front of the
MP3 controller and the RS-485 shares TB-2 with the HMI power. The HMI runs as a
Modbus RTU Master. Communication between the HMI and MP3 Controller
requires either the use of RS-232 or RS-485, but not both.
The HMI is configured to communicate with the MP3 DeviceNet Control Head using
the default communication configuration of the MP3.
MP3 Controller Modbus Address = 1
Baud Rate = 19,200
Parity/Stop = Even, 1
These settings have already been programmed into the HMI. No user action is
needed.
2.6 HMI Application
The HMI does not display a literal copy of all Modbus Coils and Registers contained
in the MP3 SCR DeviceNet Head, although many are displayed directly. Information
is accessed, arranged, displayed, written, and acted upon to perform logical tasks that
the equipment user may wish to perform. Information is presented in the form of HMI
screens. The HMI decodes the values of some monitoring data so that the meaning
may be displayed in alphanumeric form, eliminating the need to look up decoding
tables in the manual. Some information is displayed as screen indicators/messages.
Some control parameters are presented as switches. Touch screen keyboard data entry
is used with some values.
Non-volatile configuration parameters used to set up the operation of the MP3
Controller are presented in raw form using the same parameter names as used in the
MP3 manual and the EDS used with RSNetWorx for DeviceNet configuration. This
allows the HMI or RSNetWorx equal capability when configuring the controller.
Once configured, the MP3 controller is operable without the HMI or DeviceNet. The
HMI is used when a human interface is needed or to adjust calibration parameters.
DeviceNet is used when an automation interface is needed.
