Note: AL-H and AL-L include AL1H, AL2H, AL1L and AL2L. When Output 1 is set to Alarm Output, use AL1H (1024H) and AL1L
(1025H). When Output 2 is set to Alarm Output, use AL2H (1026H) and AL2L (1027H).
LED Display
1. When power is normal, POWER LED will be on.
2. After DTC1000/2000 is switched on, all LED will be on. The communication protocol will be displayed in 1 second,
followed by the communication address in the next second.
3. RUN LED is on when the control is executing.
4. ERROR LED is on when errors occur in input, memory or communication.
5. When an output is executing, its corresponding output LED will be on.
6. AT LED flashes when PID parameters are being auto-tuned.
7. RX LED flashes when DTC1000/2000 receives communication signals. TX LED flashes when DTC1000/2000
sends out communication signals.
Communication protocol displayed on LED after the power of DTC1000/2000 is switched 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 bits
1:1 Stop bit
Communication address display: AT (bit 6) and Run (bit 0) are combined to binary code.
Password Function
The default setting of the password is disabled. To enable the password function, enter the 4-character password in the
specific communication address. The password is protected by 3 levels.
1. Level 1: Only LED status, SV and PV can be read. No settings can be modified.
2. Level 2: Only LED status, SV and PV can be read. Only SV can be modified.
3. Level 3: All SV can be read. Only SV and auto-tuning can be modified.
4. Level 4: No password protection.
When a password is set (in 106EH ~ 1070H), the protection will enter Level 1. To enter other levels, enter the
corresponding password (in 106BH ~ 106DH). After DTC1000/2000 is switched off, the protection will return to Level 1.
To unlock the password protection, the user has to remove all the passwords (in 106EH ~ 1070H).
The password protection level can be read in 106EH ~ 1070H:
bit b0 b1 b2 b3 b4 b5 b6
Status Level 1
Level 2
Level 3
Level 1 locked Level 2 locked Level 3 locked Unlocked
bit = 0 refers to no password is set. bit = 1 refers to the password has been set (b0 ~ b2). b3 ~ b6 display the current level status.
Synchronous Communication Protocol & Auto ID Setup
This function allows the user to set the communication protocol of DTC2000 to the same protocol as set in the first
DTC1000. The station IDs of DTC1000/2000 are arranged in decreasing order. Follow the steps below.
1. Set the auto communication ID of DTC1000 to “1” (communication address: 1022H).
2. Switch off DTC1000 before connecting it to DTC2000. Switch it on again.
3. Default communication protocol: 9,600bps, 7 bits, Even, 1 stop bit, communication address 01.
4. This function will consume 3 ~ 5 seconds more when you switch on your DTC.
RS-485 Communication
1. Supports transmission speed: 2,400, 4,800, 9,600, 19,200, 38,400bps;
2. Does not support 7, N, 1 / 8, E, 2 / 8, O, 2 communication format;
3. Communication protocol: Modbus ASCII/RTU;
4. Function code: 03H (read Max. 8 words in register), 06H (write 1 word into register), 01H (read Max. 16 bits of
data), 05H (write 1 bit into register).
