![]() ![]() One thing that special attention is given to is ESD protection. Everything from the PCB files to the BOM is prepared and the system is ready for prototyping and further optimization. Note that there is an internal cable connecting the WiFi SMA connector to the ESP32 UFL connector which is not present in the design files. You can see this in the picture below as well. Only a few components including the connectors and the ADC chip are placed on the top side. The majority of components are installed on the bottom side as you see in the picture below. Compatible with Open PLC platform for direct PLC standard programming languages such as LADDER and FBD.Industrial temperature range -40 to +85.Din-Rail adaptor on enclosure for ease of rail and cabinet mount.Aluminum Box connected to chassis ground and PCB ground for improved ESD, EMC, and thermal performance.4-layer stack up with a solid ground plane and ground fills for improved EMC.MODBUS and CANBUS up to 1Mbps speed connectivity.Ethernet 10/100 Mbps and WiFi EEE 802.11b/g/n connectivity.8 channels 0-10 VDC analog inputs with 16-bit resolution.12 channels 24 VDC transistor outputs with overcurrent protection with LED indicator.16 channels 24 VDC inputs according to IEC61131 standard with LED indicator.ESP32-S2 embedded, Xtensa? single-core 32-bit LX7 microprocessor, up to 240 MHz with 4 MB SPI flash and 2 MB PSRAM.24VDC power supply with ideal diode reverse polarity protection.To make the device more practical I also designed an enclosure in Fusion 360 including the DIN-Rail adaptor for ease of control cabinet installation and use with the following additional features: It has some IOs built-in However, It is not limited to any number of IOs since you can increase them to large numbers using MODBUS and/or CAN bus available on Board. In this project, I designed a compact IoT PLC with WiFi and Ethernet connectivity for small to medium-sized home and industrial control applications. The client uses the same low voltage install as a video system, making it easy for the installer.If you are like me from a control engineering background and working in the world of embedded systems you definitely know about PLCs and most likely love them! I love PLCs and even more how they are actually made in practice. Unified clients are a great opportunity for integrators because it gives them new capabilities to sell that they may not have offered before, such as situational awareness and digital signage. Unified Clientsīy far the biggest takeaway of the day was the importance of moving to a unified system instead of having separate devices for access control, video surveillance, digital signage, etc. Moss believes you will be able to do reasonable video surveillance on mobile devices with the introduction of 5G. The major innovation in the network area is speed. Moss says cyberattacks today look more like planned military attacks than the stereotypical “guy in his bedroom in New Jersey.” The biggest issue in networking is cybersecurity. Moss believes adoption is slow because it isn’t as quick and accurate as card readers, emphasizing, “Access control is letting you in when you need to be let in.” However, he does believe it is perfect for use on phones and computers. However, this will allow for larger card populations and more complex programs to be put in them. Panelsīecause panels with solid state drives last so long, there hasn’t been much innovation with them aside from getting faster and being built with more memory. Moss expects to see great penetration of BLE 5 locksets in four to five years due to their ease of installation and speed. The advantage of BLE 5 over Wi-Fi is it preserves battery life longer and is faster, which will be beneficial for lockdown situations. Moss expects to see Bluetooth Low Energy 5 be released towards the end of this year. So what exactly did Moss have to say about the future of access control? Read on to find out… Electronic Locksets Using BLE 5 Hosted by CGL Security at its headquarters, based here, Moss started his presentation showing the evolution of technology, starting with the first generation of “dumb” video terminals in the 1980s, to the fourth/current generation of cloud, mobile and virtualization technology. Having created Software House over 35 years ago and now innovating at S2 Security, who better to give a presentation on its future? – SSI Industry Hall of Famer John Moss is no stranger to the world of access control. ![]()
