Description

The DL305 family is a versatile product line that provides a wide variety of features in an extremely compact package. The CPUs are small but offer many instructions normally only found in larger, more expensive systems. The modular design also offers more flexibility in the fast-moving industry of control systems. The following is a summary of the major DL305 system components.

There are three feature enhanced CPUs in this product line, the DL330, DL340, and the DL350. This manual covers the DL350 CPU only. The DL330 and DL340 CPUs are covered in detail in the DL305C User Manual. The DL350 CPU includes built-in communication ports, a large amount of program memory, a substantial instruction set, and advanced diagnostics. It also features drum timers, floating-point math, and built-in PID loops with automatic tuning.

Three base sizes are available: 5 slots, 8 slots, and 10 slots. One slot is for the CPU, the remaining slots are for I/O modules. All bases include a built-in power supply. Currently, there are two versions of the bases. The xxxxx--1 base was designed to complement the DL350 CPU. Any of the three CPUs will work in either type of base and the bases can be mixed in a system. When the DL350 CPU is used in an old base, or if it is in a system of mixed bases, it will act similar to the DL340 CPU in addressing and I/O configuration (See Appendix F).
