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
The firmwire of the 6B50 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.
The 6B50-1 and 6B50-2 can be software-configured for address, baud rate, data format, checksum status and I/O configuration. All programmable parameters are stored in the nonvolatile memory of each digital I/O board.
Inside the 6B50-1 and 6B50-2
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.
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.
