Transfer Data Between the SLC Processor and Port DH485
Use port DH485 to interface the module with the DH485 network
(other SLC processors). The commands in the following table are used
to transfer data either to or from port DH485.
Command
Purpose
MODE
Sets the port parameters of PRT1, PRT2, and DH485.
CALL 94
Displays the current port PRT1 configuration on the program port terminal
screen.
CALL 95
Retrieves the number of characters in the input or output buffer of port PRT1.
CALL 96
Clears port PRT1 input and output buffers.
CALL 103
Prints the complete output buffer with addresses, front pointer, and number
of characters in the buffer to the program port screen.
CALL 104
Prints the complete input buffer with addresses, front pointer, and number of
characters in the buffer to the program port screen.
CALL 105
Resets the port parameters of port PRT1 to their default setting.
Command
Purpose
CALL 14
Converts 16-bit signed integer located in the BASIC input buffer to BASIC
floating-point.
CALL 15
Converts 16-bit unsigned integer located in the BASIC input buffer to BASIC
floating-point.
CALL 24
Converts BASIC floating point to a 16-bit signed integer and places the result
in the BASIC output buffer.
CALL 25
Converts BASIC floating point to a 16-bit binary number and places the result
in BASIC output buffer.
CALL 27
Transfers the data from a remote DH485 data file to the SLC processor.
CALL 28
Transfers the data from the SLC processor to a remote DH485 data file.
CALL 84
Transfers the data from the DH485 common interface file to words 0 through
39 of the module input buffer.
CALL 85
Transfers words 0...39 of the module output buffer to the DH485 common
interface file.
CALL 90
Transfers the data from a remote DH485 data file to words 0...39 of the
module input buffer.
