Yaskawa MP920 Communications Module - Manual (Page 134)

6 217IF Module
6.5.4 Setting CP-217 Transmission Definitions Data
6-18
The numbers displayed in the tabs at the top of the window (CIR#nn) are the CP-217
circuit numbers. Each 217IF Module requires 3 circuits and the same circuit number
must not be used more than once.
3. Transmission Protocol
Select the desired protocol.
• MEMOBUS: Yaskawa’s standard MEMOBUS protocol.
• MELSEC: Mitsubishi’s special protocol (control protocol type 1) for use with gen-
eral-purpose sequencers and computer links.
• OMRON: OMRON’s SYSMAC C-series Host Link protocol.
• No protocol: Data can be transferred at any time by the user application program.
4. Master/Slave
When the Transmission Protocol has been set to MEMOBUS, MELSEC, or OMRON,
select whether the Machine Controller will operate as a Master or a Slave.
5. Device Address
Select the device address. When the Machine Controller is being used as a Master, set
the device address to 0. When the Machine Controller is being used as a Slave, set the
device address to a unique value between 1 and 63.
6. Serial I/F (Serial Interface)
Select the serial interface.
7. Transmission Mode
Select the transmission mode.
• RTU: Specifies RTU mode when the Transmission Protocol is set to MEMOBUS.
• ASCII: Specifies ASCII mode when the Transmission Protocol is set to MEMOBUS.
• None: Use for MELSEC, OMRON, and no-protocol communications.
8. Data Length
Select the number of bits in one character.
• 8Bit: 8 bits
• 7Bit: 7 bits
9. Parity Bit
Specify whether or not the parity bit will be used.
• Even: Even parity
• Odd: Odd parity
• None: No parity check
10. Stop Bits
Select whether there will be one or two stop bits after each byte.
• 1stop: 1 stop bit
