Input string not in correct format

[techvoipit]

Hi is the first time I have tried to connect to an OMRON PLC your software is my starting point. The manufacturer gives me PLC addresses in the following format: E0.0, E10, E200.0 ....I tried to insert in the DM DM's and CI0 but it gave me the error "Input string not in the correct format" I tried to remove E letter it responded but I think values are not correct.

That seems to be an address of an EXPANSION DM MEMORY AREA, I have never used it.

I've added some additional MemoryAreas: (There are 7 new memory areas depending on the bank) So you have to clone it again or pull the changes. It seems to be missing a WinForms example. You can download the example from CodeProject

mcOmron/mc.omron.v1.00/FINSCommands/IFinsCommand.cs

Lines 35 to 41 in 10db84a

	DME0 = 0x90,
	DME1 = 0x91,
	DME2 = 0x92,
	DME3 = 0x93,
	DME4 = 0x94,
	DME5 = 0x95,
	DME6 = 0x97,

So, have a look at ReadDM methods:

mcOmron/mc.omron.v1.00/OmronPLC.cs

Lines 173 to 184 in 10db84a

	public bool ReadDM(UInt16 position, ref UInt16 value)
	{
	// FINS command
	//
	if (!finsMemoryAreadRead(MemoryArea.DM, position, 0, 1)) return false;
	// value
	//
	value = BTool.BytesToUInt16(this._finsCmd.Response[0], this._finsCmd.Response[1]);
	return true;
	}

Now, try by adding a new method, some like ReadDME:

public bool ReadDME(MemoryArea area, UInt16 position, ref UInt16 value)
{
	if (!finsMemoryAreadRead(area, position, 0, 1)) return false;
	value = BTool.BytesToUInt16(this._finsCmd.Response[0], this._finsCmd.Response[1]);
	return true;
}

Use the proper bank area: MemoriArea.DME0, MemoriArea.DME1, ... when you call the method and remove the 'E'.

Hi now is working but
I don't understand how to address variables for example to use address E0.1 I have to use position 1 and for E200.1 what address have I to use ?
In the code value to set is a uint16 how I can write strings or int ?
Thank you in advance for the help, I attach you CX Programmer screen if can help.

You should try to find a Command reference manual, google for it, you'll find some PDF's you can download.

DM.E sounds like a Expansion Memory area. To access this memory you have to address the specific MemoryArea, it depends on your PLC model.

mcOmron/mc.omron.v1.00/FINSCommands/IFinsCommand.cs

Lines 11 to 44 in 10db84a

	public enum MemoryArea : byte
	{
	CIO_Bit = 0x30,
	WR_Bit = 0x31,
	HR_Bit = 0x32,
	AR_Bit = 0x33,
	CIO_Bit_FS = 0x70,
	WR_Bit_FS = 0x71,
	HR_Bit_FS = 0x72,
	CIO = 0xB0,
	WR = 0xB1,
	HR = 0xB2,
	AR = 0xB3,
	CIO_FS = 0xF0,
	WR_FS = 0xF1,
	HR_FS = 0xF2,
	TIM = 0x09,
	CNT = 0x09,
	TIM_FS = 0x49,
	CNT_FS = 0x49,
	TIM_PV = 0x89,
	CNT_PV = 0x89,
	DM_Bit = 0x02,
	DM = 0x82,
	DME0 = 0x90,
	DME1 = 0x91,
	DME2 = 0x92,
	DME3 = 0x93,
	DME4 = 0x94,
	DME5 = 0x95,
	DME6 = 0x97,
	TK_Bit = 0x06,
	TK = 0x46
	};

So instead of:

if (!finsMemoryAreadRead(MemoryArea.DM, position, 0, 1)) return false;

you should try something like

if (!finsMemoryAreadRead(MemoryArea.DME0, position, 0, 1)) return false;

I made some tests and now I can write/read in all variables, I have the last thing to resolve how I can write characters in a memory area ?

[mcNets]

mcOmron/mc.omron.v1.00/OmronPLC.cs

Lines 125 to 145 in 10db84a

	/// <summary>
	///
	/// MEMORY AREA READ
	///
	/// </summary>
	public bool finsMemoryAreadRead(MemoryArea area, UInt16 address, Byte bit_position, UInt16 count)
	{
	return _finsCmd.MemoryAreaRead(area, address, bit_position, count);
	}
	/// <summary>
	///
	/// MEMORY AREA WRITE
	///
	/// </summary>
	public bool finsMemoryAreadWrite(MemoryArea area, UInt16 address, Byte bit_position, UInt16 count, Byte[] data)
	{
	return _finsCmd.MemoryAreaWrite(area, address, bit_position, count, ref data);
	}

how I can convert string in byte to write memory area?

That's something that google can answer.
