Syntax
HLM_COMMAND(command, port [ , node [ , mc_area/mode [ , mc_offset
]]])
Description
The
HLM_COMMAND
command performs a specific Host link command
operation to one or to all Host Link Slaves on the selected port.
Program execution will be paused until the response string has been received
or the timeout time has elapsed. The timeout time is specified by using the
HLM_TIMEOUT
parameter. The status of the transfer can be monitored with
the
HLM_STATUS
parameter.
Notes:
•
When using the
HLM_COMMAND
, be sure to set-up the Host Link Mas-
ter protocol by using the
SETCOM
command.
•
The Host Link Master commands are required to be executed from one
program task only to avoid any multi-task timing problems.
Arguments
•
command
The selection of the Host Link operation to perform. See the table below.
command value Description
HLM_MREAD
(or value 0)
This performs the Host Link PLC
MODEL READ
(
MM
) command to read
the CPU Unit model code. The result is written to the TJ2-MC64 variable
specified by
mc_area
and
mc_offset
.
HLM_TEST
(or value 1)
This performs the Host Link
TEST
(
TS
) command to check correct com-
munication by sending string "MC__ TEST STRING" and checking the
echoed string. Check the
HLM_STATUS
parameter for the result.
HLM_ABORT
(or value 2)
This performs the Host Link
ABORT
(
XZ
) command to abort the Host link
command that is currently being processed. The
ABORT
