Application instruction format
FUN: DTLK K
K : set the port, range 0~1;
0: built-in RS485 port；
1: RS485/ RS232 expansion communication port
3.3.3 REMOTE I/O instruction
TP03 master can communicate with as many as 4 TP03 slaves with the application instruction
RMIO. Here is the briefing about this function and as for more information, please refer to
Instruction Description F191.
Item Description
communication EIA RS485 standard
Baud rate 9600bps~614400bps
Slave Max 4 slaves
Slave 1
Input: 36 points (M4200~M4235);
output: 24 points (M4600~M4623)
Slave 2
Input: 36 points (M4240~M4275);
output: 24 points (M4624~M4647)
Slave 3
Input: 36 points (M4280~M4315);
output: 24 points (M4648~M4671)
Remote I/O
(for master)
Slave 4
Input: 36 points (M4320~M4355);
output: 24 points (M4672~M4695)
Cable
Isolated twist cable, 2-wire2
Total length: 500m(76800bit/s), 1km(38400bit/s)
Note: Remote I/O slave should be TP03 basic unit rather expansion unit or other.
Application instruction:
F191: RMIO K
K port selection, range :0~1.
0: built-in RS485 port.
1: RS485/ RS232 expansion communication port
Function description:
When TP03 is set to such mode, the input and output of master can be expanded. Max slave
number is 4 in this configuration. The I/O of slave is just the expansive input and output for
master and the program in slaver will not be operated.
