4 / 70 page F-6 F-7 Equipped with functions demanded by the production site to suit a variety of applications. 2 The new CS1 can convert floating-point decimal (real numbers) to character strings (ASCII) for display on a PT (operator interface). The data can be displayed on the PT as a character string display element. The new CS1 can convert ASCII character strings read from measurement devices by serial communications to floating-point decimal data for use in data processing. Floatingpoint decimal Character string E.g., 500.00 500.00 353030E23030 Conversion instruction Floatingpoint decima Character string Conversion instruction PT Character-string display element Serial communications Measurement device (example) Convert Between Floating-point Decimal and Character Strings Nested Interlocks (for CPU Unit Ver. 2.0 or Later) Easy Cam Switch Control with Ladder Instructions (for CPU Unit Ver. 2.0 or Later) Easy Calendar Timer Function (for CPU Unit Ver. 2.0 or Later) The new CS1 can autotune PID constants with a PID control instruction. The limit cycle method is used for autotuning, so the tuning is completed quickly. This is particularly effective for multiple-loop PID control. PIDAT Autotuning for PID constants (limit cycle method) PID control instruction with autotuning PID Autotuning The new CS1 has many doubleprecision processing instructions for floating-point decimal operations, enabling positioning with greater accuracy. The SV for a timer or counter instruction can be specified using either BCD or binary. Using binary SV enables longer timers and higher-value counters. Floating-point decimal instruction High-precision positioning Ladder programs that use a lot of basic instructions can be simplified using differentiation instructions LD NOT, AND NOT, and OR NOT, and instructions that access bits in the DM and EM Areas. FAL PT (Example) An error has occurred at unit number xx. Error in Special I/O Unit FALS There is a possibility that rack number xx is disconnected. PT I/O bus error a a ● With CS1-series PLCs ● With other PLCs Error Status Generation for Debugging Simpler Ladder Programs Highly Accurate Positioning with XY Tables TIME-PROPORTIONAL OUTPUT (TPO) Instruction (for CPU Unit Ver. 2.0 or Later) A specified error status can be simulated by executing the diagnostic instructions (FAL/FALS). With the new CS1, debugging is simple for applications that display messages on a PT or other display device based on the error status of the CPU Unit.

PID S C D TPO S C B SSR Although strictly speaking the present interlock instructions do not allow nesting, applications can be created to include combination of complete and partial interlock conditions that achieve nested interlocks. Emergency stop button (1) Conveyor operates (2) Contact "a" turns ON when operator is present and products are supplied.

Compared using BCMP2 instruction * The time interval for execution by the GRY instruction is determined by the response speed for reading data from the absolute encoder.

Example: A calendar timer function can be easily set up to start a process at exactly 5:00 every evening. Examples: Timer/Counter Instructions ● TIM (BCD): 0 to 999.0 s ● TIMX (550) (binary) 0 to 6553.5 s ● CNT (BCD): 0 to 999 counts ● CNTX (546) (binary) 0 to 65,535 counts [Applicable Instructions] Timer/Counter Instructions • TIMER: TIMX (550) • COUNTER: CNTX (546) • HIGH-SPEED TIMER: TIMHX (551) • ONE-MS TIMER: TMHHX (552) • ACCUMULATIVE TIMER: TTIMX (555) • LONG TIMER: TIMLX (553) • MULTI-OUTPUT TIMER: MTIMX (554) • REVERSIBLE COUNTER: CNTRX (548) • RESET TIMER/COUNTER: CNRX (547) Easy Reading of Maintenance Data via Componet/DeviceNet The addition of special explicit message instructions makes it easy to send explicit messages without having to consider FINS commands. Transferring data among PLCs with explicit messages is also simplified. Special explicit message instruction No need to consider FINS DeviceNet CompoNet (Supported for DeviceNet Unit version 2.0 or later.) |
