![]() ![]() Cooler temps keep the balls harder and higher elevations with less air friction fly farther. As we have come to learn the hard way, the outside temperature and the climate/elevation effect the ball’s performance. We’ve all experienced ball compression diminishing with increasing humidity and temperature during tournaments. The table values shown above are not intended to be an exhaustive collection of possibilities.Ī 52COR/275lbs compression ball by definition is a sock! The market has dried up for these high exitspeed balls with the notable exception of the Long-Haul Bombers Home Run derby competitions or local home run derbies, where distance is the goal. It’s hard to find softballs today that are 525lbs compression or higher as they are found to be too hot for our senior bats. ![]() The balls that perform the best are the COR=44 or COR=47 coupled with a high compression value of 400lbs or 450lbs. ![]() Note: Don’t confuse COR with “core” which is the center of something, as they sound the same when pronounced. Remember, the higher the ball COR value is results in less barrel compression. 52 COR would reach a greater height off the pavement. Consequently, a very high COR rating will not compress the bat barrel as much, which in turn will not maximize ball-exit-speed and distance. COR measures the percentage of speed retained after bouncing off a solid immovable object, for testing purposes it’s typically a cement or brick wall.Ī softball with a high COR value, has an affinity to “bounce” off any hard surface it comes in contact with, like a solid wall or a softball bat. This value indicates how much energy is left over after the ball strikes the immovable object and then bouncing back at a speed lesser than its incoming speed. Coefficient of Restitution) is how much is given back after the impact with a solid wall during testing. A baseball is ~9.25 inches in circumference and ~2.95 inches in diameter, and weighs ~5.25 ounces.ĭefinition: Ball compression rating describes the stiffness or hardness of the ball, Coefficient of Restitution or COR, describes the “bounciness” of the ball. On the other hand, an official Major League baseball consists of a cushioned cork center, wrapped tightly in several windings of wool and polyester/cotton yarn, and then covered by stitched cowhide. The cover is sometimes leather or more commonly a composite material. a synthetic polymer) with a cover stitched and glued to the core. Unlike baseballs, softballs have an inner polyurethane ball-core (e.g. Softballs have a circumference of ~12 inches and a diameter of ~3.8 inches, and weigh about 7 ounces. a baseball are disparate in their manufacturing processes. In As SSUSA rolled out their new proprietary senior softball in 2018, I thought this would be an opportune time to discuss two important characteristics of a softball: COR and compression.

![]() ![]() Map the Tag of the Remote project to a Tag in the Local project to read this data. Once the instruction is set up to read a remote project, the "Tags of Remote Project" or "Array Tags of Remote Project" drop down lists will be accessible. The way this is accomplished is by mapping local and remote tagnames together within the local CPU's RX instruction. The greatest difference in the RX versus the MRX is that with the RX, the Tag Name in the target CPU can be referenced directly and does not need a corresponding Modbus address. To connect to other P-Series CPUs, use the RX ( Network Read) and WX ( Network Write) instructions. To connect to non Productivity Suite devices, use the MRX ( Modbus Read) and MWX ( Modbus Write) instructions. This is accomplished by having communications instructions for more than 32 devices in the ladder program and controlling the enabling and disabling of the instructions so that only 32 devices are enabled at a given time. It is possible to connect to more than 32 Modbus TCP server devices, but not concurrently. Modbus TCP Client connections: The CPU can connect to 32 Modbus TCP server devices concurrently by means of communications instructions in the ladder program (MRX, MWX, RX, WX). ![]() EtherNet/IP, Scanner/Client and Adapter/Server connections (excludes P3-530).Modbus TCP Server connections (Modbus requests received by the CPU). ![]() Modbus TCP Client connections (Modbus requests sent from the CPU).Connection to a PC running the Productivity Suite programming software.Ethernet: The Ethernet port is 10/100Base-T Ethernet with an RJ-45 style connector.Note: The USB IN port is NOT compatible with older 1.0/1.1 full speed USB devices. See Communications Connectivity for connection information. Installing the programming software will install the USB driver as well. It is used exclusively for connecting to a PC running the Productivity Suite Programming Software. USB IN: The USB IN ( P3-550 ONLY) programming port is a USB Type B style connector located on the upper left side of the P3-550 CPU.The Communication Ports are: Communication Ports Each of these ports are described in the sections below. My problem was that the messages I was sending to the server were not meeting the modbus/TCP protocol rules.The AutomationDirect P-Series CPUs are provided with several Communications Ports. Linux nc command lets you to send messages inside of TCP packets so you don't have to deal with the OSI layers. The message must be converted from hexadecimal to binary and then inserted into the data section of a TCP packet which will be sent to the server to the 502 port and over an IP packet which will contain the IP to the server. Messages must include a 7-byte header at the beginning that I was notįor example, a well formed message (represented in hexadecimal) could be: 000000000005002B0E0106Īt least, server is giving me a readable response. Third thing I was doing bad was that when modbus is over TCP, its TCP, the modbus messages must not have address byte neither errorĬheck byte and I was building the messages with that bytes on it. That a modbus service over TCP uses RTU mode. I was using ASCII but it was bad because I have found I have found that modbus protocol has 2 modes of building messages:ĪSCII and RTU. ![]() |
