Modbus Slave for SoftPLC® Runtime

; This is the configuration file for the MODBUS Slave TLM.
; Anything after a semicolon is ignored during parsing.
; There are two sections: [DRIVER] and [PORTS]:

; [DRIVER] contains global options, such as DEBUG and IOCHECK
;
; Set DEBUG to > 0 if you want diagnostic output temporarily.
;  DEBUG=0 gives no diagnostic output.
;  DEBUG=1 gives a nice Query Response trace.
;  DEBUG=2 gives what 1 does and more.
;
; Set IOCHECK to YES if you want the turn around time to be reduced by
;  having SoftPLC service the modbus commands more frequently than once
;  per scan. This is effective only when you have more rungs than
;  STARTUP.LST's oneCheckInterval setting.
;
; Set XMIT_ONLY_IF_CTS to yes if you want the transmit process to be halted
; and conditional on the CTS line being asserted by the modem
;
; Set MODEM_WARMUP_TIME to the number of msecs that the transmit process should
; wait after asserting RTS and before transmitting.  If you don't want a delay
; other than what might be required by the XMIT_ONLY_IF_CTS setting, then set
; this to zero.  MODEM_WARMUP_TIME is non-zero, and XMIT_ONLY_IF_CTS is yes,
; then both conditions must be true before transmitting takes place.
;
; Set HOLD_RTS_AFTER_LAST_BIT_USECS to the number of microseconds (usecs not msecs)
; that the driver should hold up RTS after the last byte of a reply has been
; transmitted.  This is only in affect when XMIT_ONLY_IF_CTS is set to YES.
; In one application at 1200 baud, a value of 8000 was the only one that worked.
;
; Set INTER_CHAR_GAP_COUNT to the inter character gap timeout.  If there
; is an idle gap in the command packet input stream longer than this count, then
; the internal state machine goes back to the state which looks for a match on
; the station address.  That is it goes looking for the beginning of a new packet
; and aborts any partial packet up to that point.  The units of this setting is
; "character time" which is how long it takes for one byte with stop, start and parity
; bits to travel at that given baudrate.  The modbus RTU spec calls for 4.  This
; setting only has an effect in RTU mode.  If not set, there is an internal default
; larger than zero.

[DRIVER]

; Bit mapped DEBUG word turns on selective categories of printing based on the
; bit value for each category.  Use hex to set.
; BitNum        Category
;==========     =================================================
; 0             General Debugging
; 1             Tell when RTS is toggled.
; 2             Print all REPLYs that I send in hex bytes
; 3             Print all QUERYs that I receive in hex bytes
; 4             Print timing of replies that I send
; 5             Print start of a query that is for me.
; 6             Print RX_STATE transitions
; 7             Print TX_STATE transitions
; 8             Print QUERYs that have wrong station addresses, for other nodes
; 9             Print partial quries that were victim of inter character timeouts
; 10            Print Queries that had bad CRCs.

HOLD_RTS_AFTER_LAST_BIT_USECS=8000  ; usecs time to keep RTS up after last byte we send.
;INTER_CHAR_GAP_COUNT=7             ; maximum inter character gap time in "character times"


; [PORTS] should include one line for each serial port you want active.
; All the StartAddress's must be based at element zero of a file of one
; of the following types: INTEGER, BIT, INPUT, or OUTPUT.
