Arguments • port
The specified serial port. 1 = RS-232C serial port 1; 2 = RS-422A serial
port 2.
• node
The Slave node number to send the Host link command to. Range: [0,
31].
• pc_area
The PC memory selection for the Host link command. See the first table
below.
• pc_offset
The address of the specified PC memory area to read from. Range: [0,
9999].
• length
The number of words of data to be transferred. Range: [1, 30].
• mc_area
The memory selection of the TJ1-MC__ to read the send data from. See
the second table below.
• mc_offset
The address of the specified TJ1-MC__ memory area to write to. Range
for VR variables: [0, 1023]. Range for TABLE variables: [0, 63999].
Example HLM_READ(2,17,PLC_DM,120,20,MC_TABLE,4000)
This example shows how to read 20 words from the PC DM area addresses
120-139 to TJ1-MC__'s TABLE addresses 4000-4019. The PC has Slave
node address 17 and is connected to the RS-422A port.

HLM_WRITE, SETCOM.

Type Communication parameter
Syntax HLM_STATUS PORT(n)
Description The HLM_STATUS parameter contains the status of the last Host Link Master
command sent to the specified port. The parameter will indicate the status for
the HLM_READ, HLM_WRITE and HLM_COMMAND commands. The sta-
tus bits are defined in the table below.
The HLM_STATUS will have value 0 when no problems did occur. In case of
a non-0 value, any appropriate action such as a re-try or emergency stop
needs to be programmed in the user BASIC program.
Each port has an HLM_STATUS parameter. The PORT modifier is required to
specify the port.
Arguments • n
The specified serial port. 1 = RS-232C serial port 1; 2 = RS-422A serial
port 2
Example >> HLM_WRITE(1,28,PLC_EM,50,25,MC_VR,200)
>> PRINT HEX(HLM_STATUS PORT(1))
1
Apparently the CPU Unit is in RUN mode and does not accept the write oper-
ation.
