actual physical address of the first location on the Interface
module from or to which data is to be read or written.
This function is usually used in conjunction with the
GATEWAY_CMD_ OK@ function. It returns the actual address (in
hexadecimal format) of the bit, integer, or double integer which
represents the first location on the Interface module to which or from
which data is to be transferred.
7.37 TEST_ERRLOG@ Function
The function TEST_ERRLOG@ tests the state of the error log
maintained for the application task by the Programming Executive
software. This error log can be accessed through the OnĆLine menu
of the software. The function TEST_ERRLOG@ provides a method
of checking the error log while the application task is running. This
function is cleared with CLR_ERRLOG (see 6.9.3). Note that for
Version 3.3A and later of the Programming Executive software, this
function can be entered as TESTăERRLOG@ or TSTăERRLOG@.
Format:
TEST_ERRLOG@(variable)
where:
variable is an integer variable only; used to store the number of
errors logged (1 to 3) for the task
If there are no errors logged, the result of the boolean function is
FALSE and the number parameter is indeterminant. If there are
errors, then the function is true and the variable specified is loaded
with the current number of logged errors (1 to 3). This variable must
be an integer variable.
7.38 READVAR% Function
This function requires the AutoMax operating system with the
Ethernet option.
Format:
READVAR%( vn$, value )
where:
vn$ is a string expression for the name of the variable to
read. It can be a boolean, integer, double integer,
real, or an array of these types. Only single
dimension arrays are allowed.
value is the variable where the value read is written.
This function accepts a variable name as a string expression and
returns the value in variable VALUE. The string that defines the
variable name must have a suffix as follows:
@
Booleans
% Integers
! Double integer
No suffix Reals
If specifying an array element, the subscript must be after the data
type character if there is one. Only common variables can be
accessed.
