9.608 SatService-IO-FEP2

This page describes the device driver and the device window for the SatService-IO-FEP2 device. This device monitors and controls the SatService IO-FEP controller.

The SatService-IO-FEP2 device driver is part of the sat-nms framework for M&C of plain digital I/O functions. Monitoring alarm circuits or controlling waveguide switches are indicatives for applications of this framework.

The application configuration normally does not access the SatService-IO-FEP2 device driver directly (except to access the temperature or LNA monitoring readings). There are a couple of application level logical devices (e.g. Input , Output or WG-Switch ) which may use the SatService-IO-FEP device driver as a low level driver to access the physical I/O ports.

Input ports

The variables 'inputs.0', 'inputs.1' and 'inputs.2' refer to the input ports 1..16, 17..32 and 33..48 respectively. The least significant bit in a variable reports the state of the lowest numbered port in it's group.

The variables report the logical state if the input. A bit set to '1' denotes an 'ON' or 'FLT' state, '0' stands for 'OFF' or 'OK'. The reported input states respect the 'delay' and 'invert' settings configured in the IO-FEP for each individual port.

Unused ports always report a '0', the same applies to input ports which are not licensed for this IO-FEP.

Output ports

The variable 'outputs' reports the actual state of the digital outputs and also sets the output states. The least significant bit in the variable corresponds to output 1, the most significant bit to output 16. The port states respect the 'invert' setting configured for each individual port in the IO-FEP.

Unused ports and ports which are configured in the IO-FEP as HPA muting outputs always report the state '0'. Writing to these ports will be ignored.

Beside the 'outputs' variable the IO-FEP provides 16 variables 'output.01' ... 'output.16', each reporting / commanding the state of one of the IO-FEP's outputs as 0/1. New applications should use these individual output variables instead of the common 'outputs' bitmask.

Waveguide switches

The variable 'wgstat' reports the actual state of the waveguide switches. For each waveguide switch there are 2 bits, indicating the position of the switch. '01' denotes position 'A', '10' denotes position 'B'. The bit combinations '00' and '11' both indicate a fault. This similar to the way, the physical position indicators of a waveguide switch are working. However, the bits reflect a logical state in the IO-FEP rather than the physical state of the position indicators. This is because the IO-FEP hides it's internal queuing mechanism for switch actuation's from the controlling M&C.

bit 30	0x40000000	switch 16	position A
bit 31	0x80000000	switch 16	position B

The variable 'wgcmd' is the complement to 'wgstat' for actuating the switches. In the software the bits of this variable are treated like output ports which perform the switch motor actuation. In fact, the IO-FEP monitors 0 to 1 transitions of each bit and performs the switch actuation accordingly. The actuation pulse duration is controlled by the IO-FEP, not by the sat-nms software. Nevertheless, the IO-FEP waveguide switch interface is fully compatible to the WG-Switch logical device.

Switches configured in the IO-FEP as 'unused' always report the position '00'. The same applies to switches which are not licensed for this IO-FEP.

Configuration settings

If used with the sat-nms framework for M&C of plain digital I/O functions, the SatService IO-FEP acts like an unprogrammed PLC device. It is intended, that the device driver processes switch settings and changes of input circuits as fast as possible. The following settings are necessary to achieve this:

When defining the IO-FEP device in the device setup window, there must not be defined any other devices beside the IO-FEP for this interface.
The SatService-IO-FEP2 device driver uses the Modbus/TCP protocol to communicate with the IO-FEP. The IO-FEP's IP address is configured in the device setup window as the interface for the device. It uses port number 502 (e.g. 10.0.0.1:502), the Modbus/TCP standard port number.
The IDLE time for the interface must be set to 100-200 milliseconds.
Any WG-Switch configured to work via the IO-FEP must use a pulseWidth of 1500 msecs or longer.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

--- Shows / commands I/O port states.
--- Shows the temperature readings
--- Shows the LNA monitoring readings
--- The faults page.
--- The device info page.
--- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the device.

parameter --- description
address --- Should be left empty
swCtrlFaultSrc --- Defines in which way the driver evaluates the switch control fault flag (faults.17). This fault flag tells that the IO-FEP actually is not capable to control switches or to report input signals correctly.
- COMM --- The switch control fault is determined only from the communication fault flag, the PSU fault flags are ignored.
- COMM+PSU1 --- The switch control fault is set if the IO-FEP either shows a communication fault or the primary EXT24 voltage fails.
- COMM+PSU1+PSU2 --- The switch control fault is set if the IO-FEP either shows a communication fault or both EXT24 voltages fails.
