4.3 Remote Function Block
4.3.1 Module Initialization (G3F-TC4A : TCR4INI, G4F-TC2A :TCR2INI,G6F-TC2A :TCR62INI)
The module initialization function block specifies, for use in the program, the local communications
module slot location No. of the thermocouple input module, and the station No., base No. and slot
location No. of the communications module loaded in remote I/O station. And it specifies used
channels and the type of the thermocouple.

Description
REQ BOOL
Function block execution request area
- Used to request an execution of the writing function block
- If the conditions connected with this area are established while the
program is running and “0” changes into “1” ( ), the
initialization function block is executed.
NET_
NO
USINT
Location No. of the slot where the local communication module to which
the function block will be sent is mounted.
- Setting range: 0 ~ 7
ST-N
O
USINT
Station No. of the communication module mounted in the remote I/O
station.
-Setting range: 0 ~ 63
BASE USINT
Base location No.
- Used to write the base No. where the thermocouple input module is
mounted.
- Setting range
: GM1 series(0~31), GM2 series(0~7), GM3/4 series(0-3)
GM6 series(0-1)
SLOT USINT
Slot location No.
- Used to write the slot No. where the thermocouple input module is
mounted.
- Setting range: 0~7
CH
BOOL
[Array]
*Note 1
Used channel enable/disable specification
- Used to enable or disable a channel for run.
- Specify “1” for enabling, and “0” for disabling
I
TYPE
USINT
[Array]
*Note 1
Specifying the type of used sensor
- Used to specify the type of sensor used at each channel
NDR BOOL
“1” when the function block is finished without error. “1” remains during the
scan where the execution condition is being satisfied and it changes into
“0” at the next scan.
ERR BOOL
Error information indication area
- If error occurs during initialization function block execution “1” is
outputted and the module enter into the stop state. “1” remains during
the scan where the execution condition is being satisfied and it changes
into “0” at the next scan.
STAT
USINT
Error status indication area
- Used to output the error No. when it occurs during reading function block
execution.
- For description of errors, refer to the Section 4.4
O
ACT
BOOL
[Array]
*Note 1
Run channel status indication area
- After the initialization function block is finished without error, “1” is output
if the channel is in normal state. But “0” is output for the disabled
channels.
REMARK
*Note 1: The numbers of Array are 16 in G3F-TC4A, 4 in G4F-TC2A/G6F-TC2A
