The PT returns the number of the displayed screen using the Screen Number Response Command (refer to 5-2-1 Screen Number Response). 5-1-3 Write Character-string Memory Table Format [ESC] 1B B 42 n1 n2 d1 d2 c1 c2 c3 cn n1n2: Character string length as a number of normal characters (2-digit hexadecimal) NT20M, NT2000M: 01 to 20H (1 to 32) NT600M: 01 to 28H (1 to 40) d1d2: Character-string memory table address of write destination (2-digit hexadecimal) % NT20M, NT2000M: 00 to 1FH (0 to 31) NT600M: 00 to FFH (0 to 255) c1c2c3 to cn: Character-string data Section 5-1 Description Writes the character-string data to the character-string memory table. The character-string data can contain a mixture of normal alphanumeric characters and marks. When determining the character string length, count each mark as two normal characters. If the actual character string is longer than the specified character string length, the specified number of characters is written and the remainder are discarded. A timeout error message is displayed if the actual character string is shorter than the specified character string length. Caution 5-1-4 4-digit Write Numeral Table Format [ESC] 1B C 43 d1 d2 f1 n1 n2 n3 n4 d1d2: Numeral table address of write destination (2-digit hexadecimal) NT20M, NT2000M: 00 to 7FH (0 to 127) NT600M: 00 to FFH (o to 255) f1: + (2BH) or -- (2DH) sign n1n2n3n4: Number data (4-digit BCD) Description Writes the 4-digit decimal number data to the specified numeral table. Always include a + or -- sign with the number data. The least-significant 4 digits of the display are overwritten if 4-digit number data is written to an 8-digit display. 5-1-5 8-digit Write Numeral Table Format [ESC] 1B n6 D 44 n7 d1 d2 f1 n1 n2 n3 n4 n5 n8 d1d2: Numeral table address of write destination (2-digit hexadecimal) NT20M, NT2000M: 00 to 7FH (0 to 127) NT600M: 00 to FFH (0 to 255) f1: + (2BH) or -- (2DH) sign n1n2n3n4n5n6n7n8: Number data (8-digit BCD) Description Writes the 8-digit decimal number data to the specified numeral table. Always include a + or -- sign with the number data. 5-1-6 Copy Memory Table Format [ESC] 1B / 2F m1 d1 d2 d3 s1 s2 s3 % Section 5-1 m1: Type of memory table 0 (30H): Character-string memory table 1 (31H): numeral table d1d2d3: Copy source memory table address (see table below) s1s2s3: Copy destination memory table address (see table below) Model NT20M, NT2000M NT600M Character-string memory table address 000 to 031 (3-digit BCD) 000 to 255 (3-digit BCD) Numeral table address 000 to 127 (3-digit BCD) 000 to 255 (3-digit BCD) Description Copies the contents of the copy source memory table to the copy destination memory table. The memory table contents are copied to a memory table of the same type: character-string memory table to character-string memory table or numeral table to numeral table. 5-1-7 Lamp and Touch Switch Display (Bit Specification) Format [ESC] 1B K 4B m01 m02 m11 m12 m21 m22 m31 m32 [CR] OD m0 to m3: Specification of lamps and touch switches (2-digit hexadecimal) The correspondence of the lamp and touch switch numbers to the bit representation in m0 to m3 is shown in the following table. mx2 Parameter 7 m0 m1 m2 m3 07 15 23 31 06 14 22 30 6 mx1 5 05 13 21 29 04 12 20 28 4 03 11 19 27 3 02 10 18 26 2 1 01 09 17 25 00 08 16 24 0 Bit ON: Lamp or touch switch lights (or flashes) Bit OFF: Lamp or touch switch does not light (flash) Example To light lamps and touch switch numbers 1, 5, 6, 7, and 26, m01, m02, m11, m12, m21, m22, m31, m32 = E2000004 Description Changes the lamp or touch switch lighting status.
