Description

The GE Fanuc / SBS / Greenspring IP-UD-ID / IP-UNIDIG-I IndustryPack Module with 24 Differential I/O Lines and Interrupts provides 24 flexible input/output signal lines with differential output drivers and differential inputs. Any input may be programmed to generate an interrupt. Inputs and outputs meet EIA-422 and EIA-485 specifications with an extended common mode range of +12 V to -7 V. Each line may be dynamically and individually configured for either input or output, providing maximum flexibility. Outputs may be double buffered, making the IndustryPack compatible with simulation systems requiring many outputs to be latched simultaneously. The output driver for each bit is controlled by a 24 bit register. Writing a "0" to a bit in the control register turns on the corresponding output driver. Writing a "1" turns the driver off and puts the line in a high impedance state. This is the power up default. With the driver turned off, the line may be used for input. A socketed termination resistor is placed across the plus and minus lines of each input. Each resistor is part of an eight pin SIP with four individual resistors. The socket allows the user to change the value or eliminate the termination all together. 100 Ohm resistors are the factory default.

Output lines are double buffered, with the clock source for the external latch selectable between either the internal 8 MHz IndustryPack clock or an external source with programmable polarity. The external clock source is a single ended signal, unlike the other differential I/O lines. The same clock source latches the input lines. The IndustryPack can function in a Master/Slave Mode for synchronizing multiple IndustryPacks. In this mode, the Master IndustyPack redrives the external clock source out I/O line 23. This line becomes the Master Clock, which should be wired to I/O line 24 on the Master and all Slave IndustryPacks. These features make the IndustryPack compatible with simulation systems requiring many inputs and outputs to be latched simultaneously. Slave Mode may also be used if the external clock source is differential. In this mode, only 23 I/O lines are available, as I/O line 24 becomes a dedicated clock input. The IndustryPack uses differential output latches with internal read back for verification.
