| Question: I'm doing REAL number math and OUTing the value to a register with my D3-350. When I need that number it does not display correctly. What's wrong? |
| Answer: The REAL number PLC's use the IEEE 32 bit floating point format. You must use an OUTD to store the result of a REAL number math operation into V-memory. |

| Question: I'm upgrading my old DL305 systems to the new D3-350. How will my programs be handled? |
| Answer: The D3-330 and D3-340 use the old 305 instruction set. This is early to mid-80's technology. The new D3-350 uses the new 205/405 memory mapping and instruction set. Unfortunately the only way to convert is to rewrite the program. PLC Direct technical support does not offer this service but we can refer you to integrators who can rewrite your code if you do not wish to do it yourself. |

| Question: Does the D3-350 support ASCII/BASIC modules? |
| Answer: The D3-350 CPU does not support the ASCII/BASIC modules. The D3-330 or D3-340 do. |

| Question: What modules does the D3-350 not support? |
| Answer: D3-HSC, D3-232-DCU, D3-422-DCU, D3-HP, D3-HPP, F3-AB64, F3-AB64-R, F3-AB64-T, F3-AB128, F3-AB128-R, F3-AB128-T |
| FAQ ID: 352 |
| Question: Will the D3-350 support the D3-04AD? |
| Answer: Yes, but only by using the multiplex method. You cannot use the pointer method and the PV direct access for the PID control because of the slow response of this module. |
| FAQ ID: 353 |
| Question: Will the D3-350 support the D3-02DA? |
| Answer: Yes, but only by using the multiplex method. You cannot use the pointer method and the control output direct access for the PID control because this module has only 8 bit resolution. |
