Communication speed of DEVICE is fixed to 9600, 0, 8, 1. TinyPLC has some type such as TPC32 and TPC37 model.
You have to confirm whether to RS485 Protocol by pressing '?' button of protocol option part, because communication protocol of TinyPLC's RS232 and RS485 are a little different.

READ schedule example)
| READ | STATION | Read Type | Read Start Addr | Memory Save Addr | Read Size |
| READ, | 0, | P, | 0, | 0, | 16, |
| READ, | 0, | M, | 0, | 16, | 16, |
| READ, | 0, | DW, | 0, | 32, | 16, |
1) Read Type : Memory area of TinyPLC(P, M, K, S, F, A, H, I, C, D, H, G, etc). Refer to <Table 2> about contents for detailed area.
2) STATION : Set this when use RS485 module.(0~255)
3) Read Start Address : Address position to read
4) Memory Save Address : Saving start address of Communication Server.
5) Read Size : Number of items to read at a time.
Reference) TinyPLCs has PLC for RS-232 and PLC for RS-485.

Write to direct address of controller, regardless of SCAN File.
Digital Write
Digital write setting parameters are as follows :
1) PORT Connected PORT number
2) STATION Station
3) ADDRESS Address to output
4) Extra1 Memory area to output
Write example 1) Station : 0, Address : 0000, Extra1 : P
The setting parameter shown above is digital writing example of ON/OFF point of contact for P000:0
Analog Write
Analog write setting parameters are as follows :
1) PORT Connected PORT number
2) STATION Station
3) ADDRESS Address to output
4) Extra1 Memory area to output You can output to WORD. <All areas that are listed in Table 2>
Write example 1) STATION : 0, ADDRESS : 0001, EXTRA1 : DW
The setting parameter shown above is analog writing example of changing D0001 value.
In case of using RS-232, connect as follows.
