Introduction

The PCL-745 series card provides two RS-422/485 serial ports.Each port utilizes a 16C550 UART with an on-chip 16-byte FIFO buffer for reliable, high-speed serial I/O. The UART buffer divides data into 16-byte packets before sending them onto the bus. This drastically reduces the CPU load and avoids data loss due to failure to respond to the interrupt request in time. The UART is especially useful for high speed serial I/O under Windows. The PCL-745B card differs from the PCL-743B card in that the former uses on-board optical isolators to protect your PC and equipment against damages from ground loops, increasing system reliability in harsh environments.

Introduction

PCL-800 series communication card provides reliable, high-speed serial communication. The unique shared interrupt can be set to most common (extended) AT interrupts. This simplifies programming, speeds up interrupt processing and frees up interrupts for other devices. PCL-800 series cards also provide EFT surge or isolation protection to prevent your PC and equipment against damage from ground loops, increasing system reliability in harsh environments or abrupt high voltage surges such as those caused by lightning during thunderstorms.

Siemens offers a wide range of Programmable Logic Controllers (PLC). S7-1200 PLC is suitable for small individual machine applications, whereas S7-300 PLC was previously targeted towards medium to high demand applications. However since it is nearing its end-of-lifecycle, S7-300/400 PLC series have been supplemented with the innovative S7-1500 PLC series. A new range of HMI panels are also available in all sizes for suitable operator control/monitoring. S7-1200 and S7-1500 are both part of Totally Integrated Automation (TIA) platform and programmable via Siemens TIA Portal software.
