Subject:	problem scale word data

Hi, all

for communication with PLC via using modbus, I used modbusR2-5 version.

i want to know how to scale word data.

for example.

this is Trans1.substitution file

file "../../db/mbbiDirect.template" { pattern
{P, R, PORT, OFFSET, MASK, SCAN}

{CIS:TRANS1:, YWIn10, T1_Yn_In_Word, 0x10, 0xFFFF, "I/O Intr"}
{CIS:TRANS1:, YWIn11, T1_Yn_In_Word, 0x11, 0xFFFF, "I/O Intr"}

}
file "../../db/intarray_in.template" { pattern
{P, R, PORT, NELM, SCAN}
{CIS:TRANS1:, YWIn0Array, T1_Yn_In_Word, 80, "I/O Intr"}
}
file "../../db/asynRecord.template" { pattern
{P, R, PORT, ADDR, TMOD, IFACE}
{CIS:TRANS1:, YWIn0Asyn, T1_Yn_In_Word, 0, Read, asynInt32}
}
file "../../db/statistics.template" { pattern
{P, R, PORT, SCAN}
{CIS:TRANS1:, YWIn0St, T1_Yn_In_Word, "10 second"}
}
file "../../db/poll_delay.template" { pattern
{P, R, PORT}
{CIS:TRANS1:, YWIn0PollDelay, T1_Yn_In_Word}
}

# These are the Yn outputs done with bit access. Y0-Y7
file "../../db/bo_bit.template" { pattern
{P, R, PORT, OFFSET, ZNAM, ONAM}

{CIS:TRANS1:, YWOut10, T1_Yn_Out_Word, 0x10, 0xFFFF, "I/O Intr"}
{CIS:TRANS1:, YWOut11, T1_Yn_Out_Word, 0x11, 0xFFFF, "I/O Intr"}

}
file "../../db/asynRecord.template" { pattern
{P, R, PORT, ADDR, TMOD, IFACE}
{CIS:TRANS1:, YWOut0Asyn, T1_Yn_Out_Word, 0, Read, asynInt32}
}
file "../../db/statistics.template" { pattern
{P, R, PORT, SCAN}
{CIS:TRANS1:, YWOut0St, T1_Yn_Out_Word, "10 second"}
}
file "../../db/poll_delay.template" { pattern
{P, R, PORT}
{CIS:TRANS1:, YWOut0PollDelay, T1_Yn_Out_Word}
}

and this is log file

[sjr@localhost ~]$ caget CIS:TRANS1:YWInA
CIS:TRANS1:YWInA 200
[sjr@localhost ~]$ caput CIS:TRANS1:YWOutA 250
Old : CIS:TRANS1:YWOutA 200
New : CIS:TRANS1:YWOutA 250
[sjr@localhost ~]$ caget CIS:TRANS1:YWInA
CIS:TRANS1:YWInA 250
[sjr@localhost ~]

there is need to display value of CIS:TRANS1:YWInA after change scale via using medm.

(ex. if received data from plc is 200, need to display 2.00 )

and also need to send user-input data to PLC after change scale

(ex. if user input 5.00 , need to send 500 to plc)

I need some hints for solve this problem.

regards,

JaeRyong
