The procedure to panel-mount the Profile Controller is shown in Figure 1-3. CAUTION: Do not remove the panel gasket, as this may result in inadequate clamping of the instrument in the panel. NOTE: When installing several instruments side-by-side in one cut-out, use the ratchets on the top/bottom fac...

1.3.1 Mains (Line) Input The Profile Controller will operate on 96 - 264V AC 50/60Hz mains (line) supply. The power consumption is approximately 4 VA. Power should be connected via a two-pole isolating switch (preferably situated near the equipment) and a 1A fuse. If the Profile Controller has relay...

1.3.5 Linear Inputs For linear mA input ranges, connection is made to Terminals 4 and 6 in the polarity shown in Figure 1-4. For linear mV and V ranges, connection is made to Terminals 4 and 5 in the polarity shown in Figure 1-4. For details of the linear input ranges available, refer to Appendix A....

Gently push the rear ends of the CPU PCB and Power Supply PCB apart slightly, until the two tongues on each of the Output 2/Output 3 Option PCBs become disengaged - see Figure 2-2B; The Output 2...

2.5 SELECTION OF INPUT TYPE AND OUTPUT 1 TYPE The selection of input type and Output 1 type is accomplished on link jumpers on the CPU PCB. The CPU PCB may be either of two forms: (a) for a relay, solid state or SSR drive Output 1 (see Figure 2-4) or for a DC Output 1 (see Figure 2-5). 2.5.1 Input T...

2.5.2 Primary Output (Output 1) Type The required type of Output 1 is selected by Link Jumpers LJ4, LJ5, LJ6 and LJ7 on the Relay/SSR Drive/Solid State Output 1 CPU PCB (see Figure 2-4 and Table 2-2) or, on the DC Output 1 CPU PCB, Link Jumpers LJ8 and LJ9 (see Figure 2-5 and Table 2-2). S077-2 Volu...

2.6 OUTPUT 2 TYPE/OUTPUT 3 TYPE The type of output for Output 2 and Output 3 is determined by the Option PCB fitted in the appropriate position (see Figure 2-1) and, in the case of the DC Output Option PCB being fitted, the setting of Link Jumpers LJ8 and LJ9 on that Option PCB (see Figure 2-6 and T...

If it is desired to restore the initial Controller Setpoint value after the progr...

1.7 RaPID CONTROL FEATURE The RaPID control feature may be used when extra fast responses and minimum overshoot are required. The RaPID feature works best when PID terms are well-tuned; therefore, it is recommended that the Pre-Tune feature (see Subsection 1.8) is run before the RaPID feature is eng...

4 MODBUS COMMUNICATIONS 4.1 INTRODUCTION This Section specifies the MODBUS communications protocol as implemented on the 1 16 -DIN Ramp/Soak Profile Controller. Certain restrictions have been imposed upon this implementation: (i) Baud rates may be set to 1200, 2400, 4800 and 9600 only (ii) Support f...

Number. The contents of the remainder of the message depends upon the function number. In most cases the instrument is required to reply by echoing the address and function number, together with an echo of all or part of the message received (in the case of a request to write a value or carry out a ...

This function will be used largely to report controller status information, and so a bit set to 1 indicates that the corresponding feature is currently enabled/active, and a bit reset to 0 indicates the opposite. If an exact multiple of eight bits is not requested, the data is padded with trailing z...

D. Preset Single Register (Write 1 Word) 06 B The message sent to the controller consists of 8 bytes: the address and function number as usual, the address of the parameter to be written, and the two-byte value to which the parameter will be set, and finally the CRC16. The normal response is to echo...

G. Error and Exception Responses If the controller receives a message which contains a corrupted character (parity check fail, framing error etc.), or if the CRC16 check fails, the controller ignores the message. If the message is otherwise syntactically flawed (e.g. the byte count or word count is ...

ii. Because only the remainder is of interest, the MSB (the rightmost bit) may be discarded. This means the polynomial has the value Hex A001. The CRC algorithm is as follows: 4-6 Volume II O077-4 XOR 1st 8 bits of data with MSB of result Pre-load 16-bit result with 0x0FF XOR next 8 bits of data wit...

Some of the parameters which do not apply to a particular instrument configuration (e.g. PB2 on a single output instrument) will accept reads & writes. Others will accept reads only, and will return an exception if an attempt is made to write values to them. The values read will in all cases be ...
