Turbo PMAC Program Command Specification 470

SENDA transmits the message to the Option 9T auxiliary serial port.

Note:

If a program, particularly a PLC program, sends messages immediately on power-

up/reset, it can confuse a host-computer program (such as the Turbo PMAC

Executive Program) that is trying to find Turbo PMAC by querying it and looking

for a particular response.

It is possible, particularly in PLC programs, to order the sending of messages faster than the port can

handle them. Usually, this will happen if the same SENDx command is executed every scan through the

PLC. For this reason, it is good practice to have at least one of the conditions that causes the SENDx

command to execute to be set false immediately to prevent execution of this SENDx command on

subsequent scans of the PLC.

Note:

To cause Turbo PMAC to send the value of a variable, use the COMMANDx

statement instead, specifying the name of the variable in quotes (e.g. CMDS"P1")

Examples:

SENDR"Motion Program Started"

SENDS"DONE"

SENDP"Spindle Command Given"

IF (M188=1) ; C.S.1 Warning Following Error Bit set?

IF (P188=0) ; But not set last scan? (P188 follows M188)

SENDA"Excessive Following Error" ; Notify operator

P188=1 ; To prevent repetition of message

ENDIF

ELSE ; F.E. Bit not set

P188=0 ; To prepare for next time

ENDIF

SENDS"THE VALUE OF P7 IS:" ; Turbo PMAC to send message string

CMDS"P7" ; Turbo PMAC to return the value of P7
