PLC-5/11 Controller PLC-5/20 or -5/26 Controller

keyswitch; selects controller mode

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

channel 1A status indicator (lights green and red)

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

channel 1A communication port; for the PLC-5/11 controller, the default configuration is DH+ 2

channel 1A communication port;

this 3-pin port is a dedicated DH+ port

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 1B status indicator (lights green and red)

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

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
