CS1D Programmable Controller (Duplex System)

Online Unit Replacement

When using CS1D CPU Units for either Duplex- CPU or Single-CPU Systems, Basic I/ O Units, Special I/ O Units, and CPU Bus Units can be replaced online while the power is ON and the PLC is operating. During replacement, operation of the Unit being replaced will stop, but all other Units in the system will continue operating.

Duplex Networks Improve Reliability for Increased Information

Duplex Ethernet operation increases the reliability of information system networks

Duplex operation of network lines and Communications Units is used, allowing communications to continue even if a broken line in the network occurs or one of the Communications Units fails.
Unlike systems that switch entire networks, the paths available for communications are automatically selected, allowing a network to be built with even greater reliability against broken lines in multiple locations.

The status of the connection to the Ethernet network can be monitored

The connection status for each line is always reflected in words allocated in PLC memory. This allows early detection of faulty nodes and lines in the ladder programming or at the host device, thereby improving maintenance.

Duplex Controller Link Network between PLCs

Communications will continue using the other Unit if the one Unit fails. The network is maintained by using a loopback if the network line is broken.

The CS1W- CLK12- V1 or CS1W- CLK52- V1 is required for Duplex Controller Link networks.

Program without Worrying about Duplex Operation

Duplex communications with the CS1D does not require special programming for duplex operation.

This simplifies the program design for duplex systems.

Ethernet can be used to simplify complicated programming for message communications that was previously built into applications

Controller Link can be used to configure data links with efficient area allocations

High reliability, plus high performance

The CPU units in this Duplex System feature both high performance and advanced functions, providing high reliability even to applications requiring high speed.

Space-saving compactness

The CS1D is based on medium-sized PLCs. Compared with conventional, large-sized PLCs, it saves considerable space in machines and facilities.

Seamless network environments

With the CS1D, networks are available for every level: Ethernet communications for data, Controller Link and SYSMAC LINK for controllers, and DeviceNet for components. Message can be sent and received over a maximum of three network levels.

Of course, PLC functions have also been increased

• Built-in Flash Card memory enables battery-less operation.

• Various self-diagnostic functions are included.

• A wide range of calculation functions includes floating point calculations, character string processing, and PID calculations with auto tuning.

• Structured programming (multitask and variable programming supported)
