PLC-5/40E and -5/80E Controller Front Panels

external transceiver fuse

keyswitch; selects controller mode

channel 2 Ethernet status indicator (green when functioning normally; red when not functioning)

channel 2 communication port; a 15-pin Ethernet port

channel 1A status indicator (lights green and red)

battery indicator (red when the battery is low)

controller RUN/FAULT indicator (green when running; red when faulted)

force indicator (amber when I/O forces are enabled)

channel 0 communication status indicator (green when the channel is communicating)

channel 2, Ethernet transmit indicator (green when the channel is communicating)

channel 0-25-pin D-shell serial port; supports standard EIA RS-232C and RS-423 and is RS-422A compatible 1

Use this port with ASCII or DF1 full-duplex, half-duplex master, and half-duplex slave protocols. The port's default configuration supports controller programming:

DF1 point-to-point

one stop-bit

2400 bps

BCC error check

no parity

no handshaking

8-pin mini-DIN, DH+ programming terminal connection parallel to channel 1A

channel 1A communication port; its default configuration is DH+ communication 2

channel 1B communication port; its default configuration is remote I/O scanner 2

channel 1B status indicator (lights green and red)

PLC-5/40E

Programmable

Controller

PLC-5 family member designation

1Channel 0 is optically-coupled (provides high electrical noise immunity) and can be used with most RS-422A equipment as long as:

termination resistors are not used

the distance and transmission rate are reduced to comply with RS-423 requirements

2Configure these 3-pin ports for:

remote I/O scanner

remote I/O adapter

DH+ communication

unused
