Warning, after you have programmed the D3-350 CPU, make sure you put the tiny little front panel switch in the "Run" position.
Connect your DL 305 PLC to an ICON using the D3-350 CPU.
25 pin male PLC connector | CN6 on ICON |
7 | 3 |
14 to 9 to | 2 |
16 to 10 to | 1 |
Jumper 11 to 19 | |
Jumper 7 to 18 |
Normally you would not connect to the ICON serial port 1 using RS232, but if for some reason you wish to do this proceed as following:
25 pin male PLC connector | 9 pin female ICON connector |
2 | 2 |
3 | 3 |
7 | 5 |
Jumper 4 to 5 |
After you connect the ICON to a serial port you must use your Directsoft software and configure the PLC port 2 for:
PLC registers | Modbus Address (Register address) | Modbus Type (Register type) |
Inputs (X0 to X777) | 2049-2561 | 2 to read |
Special Relays (SP0 to SP777) | 3073-3585 | 2 to read; 5 or 15 to write |
Outputs (Y0 to Y777) | 2049-2561 | 1 to read; 5 or 15 to write |
Control Relays (C0 to C1777) | 3073-4096 | 1 to read; 5 or 15 to write |
Timer Contacts (T0 to T377) | 6145-6400 | 1 to read; 5 or 15 to write |
Counter Contacts (CT0 to CT177) | 6401-6272 | 1 to read; 5 or 15 to write |
Stage Status Bits (S0 to S1777) | 5121-6144 | 1 to read; 5 or 15 to write |
Timer Current Values (V0 to V377) | 1-256 | 3 or 4 to read; 6 or 16 to write |
Counter Current Values (V1000 to V1177) | 513-640 | 3 or 4 to read; 6 or 16 to write |
V Memory, user data (V1400 to V7377) | 769-3840 | 3 or 4 to read; 6 or 16 to write |
V Memory, user data (V10000 to V17777) | 4097-8192 | 3 or 4 to read; 6 or 16 to write |
V Memory, system (V7400 to V7777 | 3481-3736 | 3 or 4 to read; 6 or 16 to write |
If you are reading A-D converter inputs you will have to write a small ladder logic program to move the A-D inputs to V user memory, say starting at V1400, that can then be read by a Modbus instruction. If you are setting D-A output values you will have to write a small ladder logic program to move the V user memory that you wrote with your Modbus command to the D-A I/O output card. Examples of writing these programs are given in the 305 analog manual.
