Modicon Programming Example - MSTR Type 2

	enable -		- active	Contents of registers in the control block

		40050		40050	= 2	Read Instruction

	abort -		- error	40051	= 0	Error Code

		40060		40052 = 13 Length of the read
				40053	= 21 slave register to read (40021)

		00020
				MBP

The MSTR instruction shown above reads the status registers (40021- 40033) from the 1560-MBP at Node Address 6, and stores the values in the processor starting at register 40060. Note that the instruction reserves 20 words for the data block, but we have chosen to only fill 13 when configuring the command.

Note that the Slave Input Path value must be entered in order for the command to execute successfully. Valid values are from 1 to 8. Any other values will cause the command to fail
