6B50-1 / 6B50-2
GENERAL DESCRIPTION
software-configured for address, baud rate, data format,
The 6B50-1 and 6B50-2 are 24-channel digital I/O boards
which are compatible with the 6B Series Signal-Conditioning
Modules at the network level. Each converts commands from
the host computer into logic levels suitable for interfacing with
industry-standard opto-isolated digital I/O panels. All I/O
channels can be configured for input or output, using bit or byte
addressing. In addition, the status of the port can be read back
by the host to confirm the I/O configuration
checksum status and I/O configuration. All programmable
parameters are stored in the nonvolatile memory of each digital
I/O board.
An on-board microcontroller communicates with the host
through an RS-232C port (Model 6B50-2 or with a 6B Series
backplane through an RS 485 port (Model 6B50-1) to exchange
command and status information.
Synchronized Sampling – The synchronized sampling
command allows data to be sampled simultaneously from all
6B11, 6B11HV, 6B12, 6B12HV modules and all 6B50 boards in a
6B Series system. Each module or board stores the data in a
separate register within its microcontroller and can access the
data with a separate command.
An included EEPROM stores system parameters (address, baud
rate, checksum, etc.) as well as I/O configuration information.
The microcontroller is interfaced to 8-bit latches and buffers a
maximum of 24 digital i/o channels. Each channel can be
individually set as either an input or output. The 6B50-1 and
6B50-2 are 3.47-inch x 6.5-inch open boards that can be panel
or rack mounted.
Software Configuration – The 6B50-1 and 6B50-2 can be
