// Example Test Script for ModScan Application
//                                            
// Each Script entry consists of the following
// comma delimited data fields:
//
// TEST NAME, NODE, FUNCTION, ADDRESS, LENGTH, DATA, CONTROL CODE
//
// Double slashes on the front of a line denote comments
//
// The following Control Codes may be used (i.e. last field on each line)
//					\ -- Continue DATA fields on next line
//					C -- Generate Bad CRC message to slave
//					D -- Check response data quantity only, (ignore actual data)
//					1 -- Expect Exception Response 01
//					2 -- Expect Exception Response 02
//					4 -- Expect Exception Response 04
//					6 -- Expect Exception Response 06
//					R -- Expect no Response
//					T (default) -- Verify Response Data
//    (Added March 2001)
//					%d -- Verify Response Data using a percentage tolerance
//						value around the expected data.  Only valid for
//						modbus function codes 03 & 04 and only valid to
//						to compare 16-bit register values.  May not be used
//						with registers containing floats, longs, etc.
// New Test:
// 		Read a single Holding Register at address 100 and
// 		compare its value to +/- 5% of 1000.  Test will pass
//		if register contains data between 950 - 1050.
//
Analog Value Test,1,3,100,1,1000,%5   
//
// First Test:
//		Write 20 Coils to Node 1 starting at address 100
//		Data is alternating pattern of ones & zeros
//      (DATA field consists of 32-bits and may be specified
//		 as a decimal, hex or floating-point value)
//
Preset Multiple Coils,1,15,100,20,0xAAAAA,T   
//
//
// Second Test:
//		Verify results of first test by reading the pattern back
//
Verify Coil Status,1,1,100,20,0xAAAAA,T
//
// Third Test:
//		Read 100 Input Status values
//		ignore the data and only verify proper quantity returned
//
Verify Input Status,1,2,100,100,0,D
//
//
// Forth Test:
//		Check Slave Response to request for 1000 registers
//		(Should probably generate an exception response)
//
Test Exception 2,1,3,100,1000,0,2
//
// Fifth Test:
//		Check Slave Response to bad CRC
//
Invalid Request,1,1,100,1,0,C
//
// Sixth Test:
//		Query an unknown device & expect no response
//
Query Device 73,73,1,1,1,0,R
//
// Seventh Test:
//		Write 6 Holding Registers with data
//      (Each floating point number represents
//		 two registers  -- The NAME field on the
//		 continuation line is ignored)
//
Write Floats,1,16,100,6,1.00,\
,2.00,3.00,,,,T
//
// Eighth Test:
//		Verify Test Seven by reading back the Registers
//
Read Floats,1,3,100,6,1.00,\
,2.00,3.00,,,,T
//
// END OF SCRIPT
