  1. hi all,

     

    so i have this trouble regarding an application that uses a v120 and enfora modem.  the plc receives messages no problem with it.   what we encounter is that when i use a different sim card for sending an sms to the plc, it receives the message but the phone number is displayed as+0918******* and not as +63918******* which has the country code.  this results in me not being able to trigger the receive bit in the plc.  i can change the number to +0918*******, to command but the problem is that the plc won't be able to reply to the said number.  has anone else experienced this?  i can use the same network and the phone number has the country code, but a different network doesn,t

  2. hi all,

    i have a question about using protocol fb. i have a phoenix empro ma250 power meter which can aommunicate using modbus rtu. i can communicate with the power meter using read holding register modbus fb flawlessly. what i want to do is use protocol fb to generate the send and receive modbus frame messages. i am having trouble constructing the messages in protocol fb. i have attached a picture of the frame structure of the meter. iam using a v350 for this, with one port for modem and the other port for the device/s. i wish to use protocol fb instead of modbus fb because i want to connect other devices that don't use modbus protocol. i hope anyone can help me.

    thanks all

  3. this might be a simple and rather silly suggestion but, can you send the mi registers directly via unican send? use bit to num to convert your digital inputs to mi registers and use num to bit in your master plc. i use this instead of struct for my programs and it works. the only problem with this is that you can only send 16 mi's per send block and this will result in multiple send routines. give this a try and see if it works
