E-880CM-1-E
1. COMMUNICATION CAPABILITY OVERVIEW
With EL4001, communication between EL4001 and the host system (personal computer, sequencer, etc.)
is available via RS-485. By communication, you can read the information displayed in the RUN mode,
read/write the setup parameters in the SET and/or SYS mode, or by popping the key card into the drive,
you can read/write the viscosity, density, and liquid kind you want to set up.
●
No handshake: Nonprocedural
●
One master to n slaves: n-multipoint communication (n: a maximum of 16 units)
●
Compatible with local/remote selection : Shown on the LCD screen
※
We do not offer software support for higher-level systems.
2. NETWORK CONFIGURATION
A higher-level (host) system (PC, sequencer, etc.) and lower-level systems (EL4001) are connected in a
network shown below.
※
Be sure to connect a terminating resistance (100
Ω
approx.) at both ends of the cable. EL4001 has a
100
Ω
terminating resistor internally. At the end of communication channel, place the DIP switch at the
rear in the ON position; at an intermediate point in the channel, place it in the OFF position.
