Attention: AL-H and AL-L include AL1H, AL2H and AL1L, AL2L. When the 1
st
group output is set to alarm output, AL1H (1024H) and AL1L (1025H)
will be used. When the 2
nd
group output is set to alarm output, AL2H (1026H) and AL2L (1027H) will be used.
 LED Display
1. When power is normal, POWER LED will be lit.
2. LED will be lit after power on. Within one second after power on, communication protocol will be displayed; and at
the following second after communication protocol displayed, communication address will be displayed. After that,
LED will all be lit to show operation is normal.
3. When control action is executing, RUN LED will be lit.
4. When input, memory, or communication happens to error, ERROR LED will be lit.
5. When output is acted, the corresponding LED will be lit.
6. When PID program is auto adjusting parameter, AT LED will blink.
7. RX LED will blink when receiving communication signal and TX LED will blink when transmitting communication
signal.
Protocol Format of LED Display When Power On
AT TX RX O1 O2 Err Run
000: 2,400bps 001: 4,800bps 010: 9,600bps
011: 19,200bps 100: 38,400bps
Parity 00: None 01: Even
10: Odd
0: ASCII
1: RTU
0:2 Stop bit
1:1 Stop bit
Communication address display: AT (bit 6) and Run (bit 0) will combine to binary code.
 Password Function
The default of password will not operate. After writing 4-byte password into specific communication address, password
function will be activated. There are three levels for password protection:
1. Level1: only LED status, settings, and input values can be read via communication. It is unable to revise anything.
2. Level2: only LED status, settings, and input value can be read via communication. Also, it is able to revise setting.
3. Level3: all the settings can be read via communication, but it is only revisable for settings and AT adjustment.
4. No password function.
Once password is set (106EH ~ 1070H), the controller will enter level 1. For entering another level, please key in
corresponding password in 106BH ~ 106DH (see Address and content of Data Register). After power off, it will get back
to level one. If password protection function shall be dismissed, it is necessary to clear all password setting.
To enable password function, it is necessary to write corresponding password (106EH ~ 1070H) when password status
is dismissed. To dismiss password levels, intended password setting should be written in specific function address
106EH ~ 1070H.
Password status can be read from 106EH~1070H. Statuses corresponding to each bit are shown as the following table:
Bit b0 b1 b2 b3 b4 b5 b6
Status Level 1 Level 2 Level 3 Level 1 locked Level 2 locked Level 3 locked Unlock
Bit = 0 means no password setting. Bit = 1 means password is set (b0 ~ b2). b3 ~ b6 are used for displaying current
password status.
 Synchronous Communication Protocol & Auto Number ID
By using Auto Number ID function, the communication protocol of DTC2000 can be set the same as the one of
DTC1000. ID numbers tend to increase.
1. Set the auto communication flag to be “1” for DTC1000 (communication address 1022H).
2. Switch off the controller before connecting to another DTC2000. After that, switch on the power again.
3. Communication default: 9600bps, 7bits, Even, 1 stop bit.
4. This function will result in additional 3~5 seconds for power on.
 RS-485 Communication
1. Supporting transmission speed: 2,400, 4,800, 9,600, 19,200, 38,400bps.
2. Non-supported formats: 7, N, 1 or 8, E, 2 or 8, O, 2.
3. Communication protocol: Modbus (ASCII or RTU)
4. Function code: 03H to read the content of register (max. 8 words). 06H to write one word into register. 01H to read
bits data (max. 16 bits). 05H to write one bit to register.
5. Address and Content of Data Register:

LRC Check:
LRC check is the added sum from “Machine Address” to “Data content”. For example, 01H + 03H + 10H+ 00H + 00H + 02H
= 16H, then take the complementary of 2 to get EA.
