Delta RMC151 - Manual (Page 421)

6 Communication
series motion controllers. It also describes how to configure the communications and the
basics of actually communicating, such as issuing commands, writing and reading, etc.
Example programs for certain HMIs are available on the downloads page of Delta's website.
These can help you get up and running quickly.
Requirements of the HMI
Requirement 1: Must Support a Compatible Protocol
The HMI must support a protocol that is compatible with the specific RMC. Notice that
certain protocols have specific requirements that the HMI must also fulfill.
Comm Type/
RMC
Supported
Protocols Notes
Ethernet:
RMC75E
RMC150E CPU CSP (Allen-Bradley) Must support registers F7 to
F255
EtherNet/IP (Allen-Bradley) Must support registers F7 to
F255
FINS/UDP (Omron)
Modbus/TCP Preferably support up to
address 65535.
Serial:
RMC75S
RMC75P Monitor
Port
DF1 (Full- and Half-Duplex) (Allen-
Bradley)
Must support registers F7 to
F255
Modbus/RTU Preferably support up to
address 65535.
PROFIBUS-DP:
RMC75P
RMC150E PROFIBUS-DP
Requirement 2: 32-bit Floating Point Support
The HMI must support 32-floating point numbers. The HMI must be able to write
individual floating-point numbers and read individual floating-point numbers. In order to
issue commands to the RMC, the HMI must also be able to write to multiple floating-point
numbers at once.
Optional Requirement 3:
The HMI should be able to view individual bits in a register read via Modbus/TCP or
Modbus/RTU, or view individual bits in an F register read via CSP or DF1. This allows the
HMI to display status items such as Axis Enabled, Halted, etc.
Configuring the HMI Communications
Using Ethernet:
For most devices, use Modbus/TCP. If that option is not available, set up the HMI
communications as if it were talking to a SLC 500 PLC using CSP or EtherNet/IP.
For more details on setting up ethernet, see the Ethernet Overview topic.
Using Serial RS-232 or RS-485:
For most devices, use Modbus/TCP. If that option is not available, set up the HMI
communications as if it were talking to a PLC. When selecting the protocol, choose an
Allen-Bradley SLC 500 PLC with DF1. If the SLC500 is not available, choose a PLC-5 or a
MicroLogix.
If you are connecting the HMI to the RS-232 Monitor port on the RMC75S or RMC75P,
make sure the PLC communication settings are identical to the RS-232 Monitor Port
settings: DF1 Full-Duplex, 38400 Baud, 8 Data Bits, No Parity, 1 Stop Bit, CRC.
