About 1785-L80B

On the 1785-L80B, the Data Highway Plus (DH+) link can be used on all four existing channels. DH+ communication can be used for data transfer to other PLC-5 controllers or other higher-level components of the control system. The DH+ link can program multiple PLC-5 controllers. On the front panel of the 1785-L80B controller, there is a 25-pin connector marked channel 0. This is an optically isolated EIA RS232C port. Channel 0 supports ASCII and DF1 full and half-duplex master and half-duplex slave protocols. On the front panel is a green channel 0 communication indicator light. Beside channel 0, there are two 8-pin mini-DIN connectors marked as channel 1A and channel 2A, and there is a DH+ programming terminal connection parallel to channels 1A and 2A. There are four three-pin connectors used as communication ports. These three-pin connectors are used for channel 1A, 1B, 2A, and 2B. All of these ports can function as remote I/O scanners, remote I/O adapters, or as DH+ communication ports. The maximum cable length for the DH+ link depends on the transmission rate. It is crucial that all devices on a DH+ link communicate at the same rate. That length goes from a maximum 3048m for speed 57.6 kilobits per second, to 762m for a speed of 230.4 kilobits per second. The 1785-L80B has several indicators on the front panel for easy interaction. Indicators display various controller statuses. The indicator marked BATT displays the status of the battery. The indicator marked PROC indicates the current controller mode, it is green when the controller is in RUN mode, and red when something is wrong. The FORCE indicator is amber when the I/O forces are enabled. The COMM indicator is linked with channel 0's communication status. The indicator is green when the channel is communicating. All four communication channels: 1A, 1B, 2A, and 2B, have dedicated status indicators.
