    "Optional Modbus RTU interface on RS-485, FC03, FC06 and FC16. All data is in holding registers (the document calls the memory type 40000). The document numbers registers from 1 (PLC addresses), so the addresses are 1-based (address on the wire = number minus 1).",
    "Baud rate is 9600, 19200 or 38400 bit/s with 8 data bits, no parity and 2 stop bits. The document gives no factory default for the baud rate or the slave address; 9600 and 1 are assumed here.",
    "The device is an eight-input analog indicator. Measurements, alarm values and scale limits are integers from -9999 to 9999 and the number of decimal places of each input (registers 28, 32, 36 ... 56) moves the decimal point, so they are given as raw values.",
    "The status bits in registers 1009 and 1010 are numbered 1, 2, 4 and 2, 4, 5 in the document, which does not say whether bit 0 or bit 1 is the first. They are entered as printed: check them on a device.",
    "Registers 17 and 18 are reserved and not in this map. The document is dated 2010 and the second part is the DNP 3.0 profile, which is not mapped.",
    "Written from the manufacturer's document for firmware 1.03; not tested on a device."
