GE DS200RTBAG1A Gas turbine characteristic module

This section provides a list of the reference material used in the preparation of this manual.This appendix provides hints and suggestions to aid developers of application I/O hardware targeted for the Twisted Pair Control Modules. The I/O circuit designer is constrained by the programming model and internal hardware of the Neuron Chip. The constraints on I/O pin usage are defined in Reference

The AIB does not buffer the 11-I/O and ~SERVICE pins of the Neuron Chip. The ~SERVICE signal only reaches the interface adapter if the JP4 jumper marked on the AIB is installed. The ~RESET signal on the AIB is a buffered CMOS input to the Neuron Chip on the Emulator. This buffering does not allow direct testing of an I/O circuit using ~RESET as an output from the Neuron Chip

State Transition Timing

 The state transition timing for Neuron Chip I/O signals after reset depends on the external memory included in the node implementation. The control modules contain a fixed set of memory resources which do not include external RAM. Therefore, the I/O state transitions during reset are bounded by the slowest input clock frequency, 5MHz. Figure 14 shows typical I/O state transition behavior for a 5 MHz module during reset. The TP/FT-10F, TP/XF-78F, and TP/XF-1250 modules running at 10MHz will take roughly 61ms to achieve the initial I/O pin state after the rising edge of the reset signal.

MAI Considerations

 The LonBuilder and NodeBuilder tools include a Model 21860 Module Application Interface (MAI) and cable that can be used in place of a twisted pair control module for testing your target device. The cable connects the MAI to a LonBuilder Application Interface Board or a NodeBuilder LTM-10 Node.The MAI has two jumpers to control the power distribution for the I/O circuit under development. If JP1 is installed, the I/O circuit under development can use up to 400 mA of regulated +5V from the LonBuilder processor board or NodeBuilder LTM-10 Node through the pin P1.12. If JP2 is installed, 35 mA of regulated +12V from the LonBuilder processor board is available through pin P1.1 (+12V is not available on the LTM-10 node). If the power supply circuit for the target device sources the power, JP1 and JP2 must be removed.
