The PCS7 redundant system communicates with the IM151-8PN/DPCPU (with CPU) via the PROFINET protocol. How do you configure it in the hardware configuration of the PCS7? I want PCS7 to be the master, IM151-8PN/DPCPU to do the slave. How to configure CP443 in redundant main station? Agricultural Machinery Accessories Parts
Agricultural machinery parts more generally summarizes the machinery parts associated with agricultural production, the coverage is very wide. Such as: tractor power mechanical parts, tires, bucket, etc., harvester including potato harvester, peanut harvester, agricultural machinery and tools (pear. Take the plough as an example, the plough includes the disc plough, moldshare plough, animal force plough, the component of the whole machine includes the plow tip, the plow leg, the plow share, the plow piece and so on. Related industries, the production of supporting products accessories can be called agricultural machinery accessories.
What are common agricultural machinery accessoriesNow rural use of agricultural machinery is common, in the job, because of farmland environment is bad, so most of farm machinery accessories used are consumables, need to change regularly, in order to avoid failure, farm machinery accessories usually used are:1, agricultural tiresQualified agricultural tires tues both sides have the trademark, model, specification, layer number and the cord material etc, and clear, eye-catching, some still carries with production and inspection chapter; Inner surface should be smooth with brightness, the hand has the elasticity. If the tyre surface identification is not complete or fuzzy, inner tube lacklustre, tire body thin and uneven thickness, hand inelastic, is defective.2, threadProduct appearance should be bright and clean without rust, without defects, continuous spiral arm, no burr, no crack. Will be specimen and standard accessories spinning together, should be able to spin to the terminal, and no card lag phenomenon in the process of precession; Spin after flipping the fittings should be without shaking and sound, and if the thread has defects such as corrosion, crack, burr, spin the move after fitting will shake, for inferiority of quality.3, the gearQualified gear packing should be in good condition, tooth surface should be smooth and no cutting marks, no burr, and coated with anti-rust oil or wax, gear profile usually have code, with a hacksaw blade broken crop row gear face, should be no scratches or only a fine scratches. If the gear surface have burr, notching, rust, sharp strokes with sawdust and Nick (insufficient hardness), the poor quality.4, V beltQualified V belt surface is smooth, seamless joint glue, outside the circle on a clear trademark, specification, manufacturer name and logo, the length of the same type of V belt should be consistent.If the V belt look rough, uneven glue joint or openings, shade thrum exposed edges, no marks or blur, the V belt length is differ, it is false and inferior product.5, V belt wheelQualified V belt wheel surface porosity, crack, grooved smooth, V belt buckle grooved, V belt is slightly higher than that of slot and the bottom of the V belt is not drain contact. If discover wheel blowhole defects such as trough, the groove surface shape and qualified V belt do not form a complete set, it is bad.

Answer: 1. The PCS7 redundant H system has two sets of CP443-1 Ethernet communication module RJ45 sockets; and the IM151-8PN/DPCPU integrates three PROFINET protocols with RJ45 sockets, so it can communicate using S7 protocol (S7Connection).
2. Since the IM151-8PN/DPCPU does not support the redundant connection configuration communication (RredundantConnection), the IM151-8PN/DPCPU needs to be connected to the two CPU modules in the H system for communication configuration connection; also in the H system and IM151. Two sets of communication data transceiver programs are written on both sides of the -8PN/DPCPU.
3. After the S7Connection configuration is established bilaterally, the communication data transceiver program can be programmed on the IM151-8PN/DPCPU side by calling the FB12 (BSEND)/FB13 (BRCV) block; the SFB12 (BSEND)/SFB13 can be called on the H system side. BRCV) block to write communication data transceiver program.
4. Remember to write two sets of communication data transceiver programs on both sides of the H system and the IM151-8PN/DPCPU, just change the different connection IDs (see illustration)!
